Another merge. Only doc stuff was affected (but this aligns the UTF-32

codec changes in trubk and branch).  Hopefully the Py3k glossary wasn't
different from the trunk one.

+   byte code
+      The internal representation of a Python program in the interpreter. The
+      byte code is also cached in ``.pyc`` and ``.pyo`` files so that executing
+      the same file is faster the second time (recompilation from source to byte
+      code can be avoided).  This "intermediate language" is said to run on a
+      "virtual machine" that calls the subroutines corresponding to each
+      bytecode.
+    
+   classic class
+      Any class which does not inherit from :class:`object`.  See
+      :term:`new-style class`.
+    
+   coercion
+      The implicit conversion of an instance of one type to another during an
+      operation which involves two arguments of the same type.  For example,
+      ``int(3.15)`` converts the floating point number to the integer ``3``, but
+      in ``3+4.5``, each argument is of a different type (one int, one float),
+      and both must be converted to the same type before they can be added or it
+      will raise a ``TypeError``.  Coercion between two operands can be
+      performed with the ``coerce`` builtin function; thus, ``3+4.5`` is
+      equivalent to calling ``operator.add(*coerce(3, 4.5))`` and results in
+      ``operator.add(3.0, 4.5)``.  Without coercion, all arguments of even
+      compatible types would have to be normalized to the same value by the
+      programmer, e.g., ``float(3)+4.5`` rather than just ``3+4.5``.
+    
+   complex number
+      An extension of the familiar real number system in which all numbers are
+      expressed as a sum of a real part and an imaginary part.  Imaginary
+      numbers are real multiples of the imaginary unit (the square root of
+      ``-1``), often written ``i`` in mathematics or ``j`` in
+      engineering. Python has builtin support for complex numbers, which are
+      written with this latter notation; the imaginary part is written with a
+      ``j`` suffix, e.g., ``3+1j``.  To get access to complex equivalents of the
+      :mod:`math` module, use :mod:`cmath`.  Use of complex numbers is a fairly
+      advanced mathematical feature.  If you're not aware of a need for them,
+      it's almost certain you can safely ignore them.
+    
+   descriptor
+      Any *new-style* object that defines the methods :meth:`__get__`,
+      :meth:`__set__`, or :meth:`__delete__`. When a class attribute is a
+      descriptor, its special binding behavior is triggered upon attribute
+      lookup.  Normally, writing *a.b* looks up the object *b* in the class
+      dictionary for *a*, but if *b* is a descriptor, the defined method gets
+      called. Understanding descriptors is a key to a deep understanding of
+      Python because they are the basis for many features including functions,
+      methods, properties, class methods, static methods, and reference to super
+      classes.
+    
+   dictionary
+      An associative array, where arbitrary keys are mapped to values.  The use
+      of :class:`dict` much resembles that for :class:`list`, but the keys can
+      be any object with a :meth:`__hash__` function, not just integers starting
+      from zero.  Called a hash in Perl.
+    
+   duck-typing
+      Pythonic programming style that determines an object's type by inspection
+      of its method or attribute signature rather than by explicit relationship
+      to some type object ("If it looks like a duck and quacks like a duck, it
+      must be a duck.")  By emphasizing interfaces rather than specific types,
+      well-designed code improves its flexibility by allowing polymorphic
+      substitution.  Duck-typing avoids tests using :func:`type` or
+      :func:`isinstance`. Instead, it typically employs :func:`hasattr` tests or
+      :term:`EAFP` programming.
+    
+   EAFP
+      Easier to ask for forgiveness than permission.  This common Python coding
+      style assumes the existence of valid keys or attributes and catches
+      exceptions if the assumption proves false.  This clean and fast style is
+      characterized by the presence of many :keyword:`try` and :keyword:`except`
+      statements.  The technique contrasts with the :term:`LBYL` style that is
+      common in many other languages such as C.
+
+   extension module
+      A module written in C, using Python's C API to interact with the core and
+      with user code.
+    
+   __future__
+      A pseudo module which programmers can use to enable new language features
+      which are not compatible with the current interpreter.  For example, the
+      expression ``11/4`` currently evaluates to ``2``. If the module in which
+      it is executed had enabled *true division* by executing::
+    
+         from __future__ import division
+    
+      the expression ``11/4`` would evaluate to ``2.75``.  By importing the
+      :mod:`__future__` module and evaluating its variables, you can see when a
+      new feature was first added to the language and when it will become the
+      default::
+    
+         >>> import __future__
+         >>> __future__.division
+         _Feature((2, 2, 0, 'alpha', 2), (3, 0, 0, 'alpha', 0), 8192)
+
+   garbage collection
+      The process of freeing memory when it is not used anymore.  Python
+      performs garbage collection via reference counting and a cyclic garbage
+      collector that is able to detect and break reference cycles.
+    
+   generator
+      A function that returns an iterator.  It looks like a normal function
+      except that values are returned to the caller using a :keyword:`yield`
+      statement instead of a :keyword:`return` statement.  Generator functions
+      often contain one or more :keyword:`for` or :keyword:`while` loops that
+      :keyword:`yield` elements back to the caller.  The function execution is
+      stopped at the :keyword:`yield` keyword (returning the result) and is
+      resumed there when the next element is requested by calling the
+      :meth:`next` method of the returned iterator.
+    
+      .. index:: single: generator expression
+    
+   generator expression
+      An expression that returns a generator.  It looks like a normal expression
+      followed by a :keyword:`for` expression defining a loop variable, range,
+      and an optional :keyword:`if` expression.  The combined expression
+      generates values for an enclosing function::
+    
+         >>> sum(i*i for i in range(10))         # sum of squares 0, 1, 4, ... 81
+         285
+    
+   GIL
+      See :term:`global interpreter lock`.
+    
+   global interpreter lock
+      The lock used by Python threads to assure that only one thread can be run
+      at a time.  This simplifies Python by assuring that no two processes can
+      access the same memory at the same time.  Locking the entire interpreter
+      makes it easier for the interpreter to be multi-threaded, at the expense
+      of some parallelism on multi-processor machines.  Efforts have been made
+      in the past to create a "free-threaded" interpreter (one which locks
+      shared data at a much finer granularity), but performance suffered in the
+      common single-processor case.
+    
+   IDLE
+      An Integrated Development Environment for Python.  IDLE is a basic editor
+      and interpreter environment that ships with the standard distribution of
+      Python.  Good for beginners, it also serves as clear example code for
+      those wanting to implement a moderately sophisticated, multi-platform GUI
+      application.
+    
+   immutable
+      An object with fixed value.  Immutable objects are numbers, strings or
+      tuples (and more).  Such an object cannot be altered.  A new object has to
+      be created if a different value has to be stored.  They play an important
+      role in places where a constant hash value is needed, for example as a key
+      in a dictionary.
+    
+   integer division
+      Mathematical division discarding any remainder.  For example, the
+      expression ``11/4`` currently evaluates to ``2`` in contrast to the
+      ``2.75`` returned by float division.  Also called *floor division*.
+      When dividing two integers the outcome will always be another integer
+      (having the floor function applied to it). However, if one of the operands
+      is another numeric type (such as a :class:`float`), the result will be
+      coerced (see :term:`coercion`) to a common type.  For example, an integer
+      divided by a float will result in a float value, possibly with a decimal
+      fraction.  Integer division can be forced by using the ``//`` operator
+      instead of the ``/`` operator.  See also :term:`__future__`.
+    
+   interactive
+      Python has an interactive interpreter which means that you can try out
+      things and immediately see their results.  Just launch ``python`` with no
+      arguments (possibly by selecting it from your computer's main menu). It is
+      a very powerful way to test out new ideas or inspect modules and packages
+      (remember ``help(x)``).
+    
+   interpreted
+      Python is an interpreted language, as opposed to a compiled one.  This
+      means that the source files can be run directly without first creating an
+      executable which is then run.  Interpreted languages typically have a
+      shorter development/debug cycle than compiled ones, though their programs
+      generally also run more slowly.  See also :term:`interactive`.
+    
+   iterable
+      A container object capable of returning its members one at a
+      time. Examples of iterables include all sequence types (such as
+      :class:`list`, :class:`str`, and :class:`tuple`) and some non-sequence
+      types like :class:`dict` and :class:`file` and objects of any classes you
+      define with an :meth:`__iter__` or :meth:`__getitem__` method.  Iterables
+      can be used in a :keyword:`for` loop and in many other places where a
+      sequence is needed (:func:`zip`, :func:`map`, ...).  When an iterable
+      object is passed as an argument to the builtin function :func:`iter`, it
+      returns an iterator for the object.  This iterator is good for one pass
+      over the set of values.  When using iterables, it is usually not necessary
+      to call :func:`iter` or deal with iterator objects yourself.  The ``for``
+      statement does that automatically for you, creating a temporary unnamed
+      variable to hold the iterator for the duration of the loop.  See also
+      :term:`iterator`, :term:`sequence`, and :term:`generator`.
+    
+   iterator
+      An object representing a stream of data.  Repeated calls to the iterator's
+      :meth:`next` method return successive items in the stream.  When no more
+      data is available a :exc:`StopIteration` exception is raised instead.  At
+      this point, the iterator object is exhausted and any further calls to its
+      :meth:`next` method just raise :exc:`StopIteration` again.  Iterators are
+      required to have an :meth:`__iter__` method that returns the iterator
+      object itself so every iterator is also iterable and may be used in most
+      places where other iterables are accepted.  One notable exception is code
+      that attempts multiple iteration passes.  A container object (such as a
+      :class:`list`) produces a fresh new iterator each time you pass it to the
+      :func:`iter` function or use it in a :keyword:`for` loop.  Attempting this
+      with an iterator will just return the same exhausted iterator object used
+      in the previous iteration pass, making it appear like an empty container.
+    
+   LBYL
+      Look before you leap.  This coding style explicitly tests for
+      pre-conditions before making calls or lookups.  This style contrasts with
+      the :term:`EAFP` approach and is characterized by the presence of many
+      :keyword:`if` statements.
+    
+   list comprehension
+      A compact way to process all or a subset of elements in a sequence and
+      return a list with the results.  ``result = ["0x%02x" % x for x in
+      range(256) if x % 2 == 0]`` generates a list of strings containing hex
+      numbers (0x..) that are even and in the range from 0 to 255. The
+      :keyword:`if` clause is optional.  If omitted, all elements in
+      ``range(256)`` are processed.
+    
+   mapping
+      A container object (such as :class:`dict`) that supports arbitrary key
+      lookups using the special method :meth:`__getitem__`.
+    
+   metaclass
+      The class of a class.  Class definitions create a class name, a class
+      dictionary, and a list of base classes.  The metaclass is responsible for
+      taking those three arguments and creating the class.  Most object oriented
+      programming languages provide a default implementation.  What makes Python
+      special is that it is possible to create custom metaclasses.  Most users
+      never need this tool, but when the need arises, metaclasses can provide
+      powerful, elegant solutions.  They have been used for logging attribute
+      access, adding thread-safety, tracking object creation, implementing
+      singletons, and many other tasks.
+    
+   mutable
+      Mutable objects can change their value but keep their :func:`id`.  See
+      also :term:`immutable`.
+    
+   namespace
+      The place where a variable is stored.  Namespaces are implemented as
+      dictionaries.  There are the local, global and builtin namespaces as well
+      as nested namespaces in objects (in methods).  Namespaces support
+      modularity by preventing naming conflicts.  For instance, the functions
+      :func:`__builtin__.open` and :func:`os.open` are distinguished by their
+      namespaces.  Namespaces also aid readability and maintainability by making
+      it clear which module implements a function.  For instance, writing
+      :func:`random.seed` or :func:`itertools.izip` makes it clear that those
+      functions are implemented by the :mod:`random` and :mod:`itertools`
+      modules respectively.
+    
+   nested scope
+      The ability to refer to a variable in an enclosing definition.  For
+      instance, a function defined inside another function can refer to
+      variables in the outer function.  Note that nested scopes work only for
+      reference and not for assignment which will always write to the innermost
+      scope.  In contrast, local variables both read and write in the innermost
+      scope.  Likewise, global variables read and write to the global namespace.
+    
+   new-style class
+      Any class that inherits from :class:`object`.  This includes all built-in
+      types like :class:`list` and :class:`dict`.  Only new-style classes can
+      use Python's newer, versatile features like :attr:`__slots__`,
+      descriptors, properties, :meth:`__getattribute__`, class methods, and
+      static methods.
+    
+   Python 3000
+      Nickname for the next major Python version, 3.0 (coined long ago when the
+      release of version 3 was something in the distant future.)
+
+   reference count
+      The number of places where a certain object is referenced to.  When the
+      reference count drops to zero, an object is deallocated.  While reference
+      counting is invisible on the Python code level, it is used on the
+      implementation level to keep track of allocated memory.
+    
+   __slots__
+      A declaration inside a :term:`new-style class` that saves memory by
+      pre-declaring space for instance attributes and eliminating instance
+      dictionaries.  Though popular, the technique is somewhat tricky to get
+      right and is best reserved for rare cases where there are large numbers of
+      instances in a memory-critical application.
+    
+   sequence
+      An :term:`iterable` which supports efficient element access using integer
+      indices via the :meth:`__getitem__` and :meth:`__len__` special methods.
+      Some built-in sequence types are :class:`list`, :class:`str`,
+      :class:`tuple`, and :class:`unicode`. Note that :class:`dict` also
+      supports :meth:`__getitem__` and :meth:`__len__`, but is considered a
+      mapping rather than a sequence because the lookups use arbitrary
+      :term:`immutable` keys rather than integers.
+
+   type
+      The type of a Python object determines what kind of object it is; every
+      object has a type.  An object's type is accessible as its
+      :attr:`__class__` attribute or can be retrieved with ``type(obj)``.
+    
+   Zen of Python
+      Listing of Python design principles and philosophies that are helpful in
+      understanding and using the language.  The listing can be found by typing
+      "``import this``" at the interactive prompt.

-generator expression
-   An expression that returns a generator.  It looks like a normal expression
-   followed by a :keyword:`for` expression defining a loop variable, range, and an
-   optional :keyword:`if` expression.  The combined expression generates values for
-   an enclosing function::
-
-      >>> sum(i*i for i in range(10))         # sum of squares 0, 1, 4, ... 81
-      285

-   .. index:: single: GIL
-
-GIL
-   See *global interpreter lock*.
-
-   .. index:: single: global interpreter lock
-
-global interpreter lock
-   The lock used by Python threads to assure that only one thread can be run at
-   a time.  This simplifies Python by assuring that no two processes can access
-   the same memory at the same time.  Locking the entire interpreter makes it
-   easier for the interpreter to be multi-threaded, at the expense of some
-   parallelism on multi-processor machines.  Efforts have been made in the past
-   to create a "free-threaded" interpreter (one which locks shared data at a
-   much finer granularity), but performance suffered in the common
-   single-processor case.
-
-   .. index:: single: IDLE
-
-IDLE
-   An Integrated Development Environment for Python.  IDLE is a basic editor and
-   interpreter environment that ships with the standard distribution of Python.
-   Good for beginners, it also serves as clear example code for those wanting to
-   implement a moderately sophisticated, multi-platform GUI application.
-
-   .. index:: single: immutable
-
-immutable
-   An object with fixed value.  Immutable objects are numbers, strings or tuples
-   (and more).  Such an object cannot be altered.  A new object has to be created
-   if a different value has to be stored.  They play an important role in places
-   where a constant hash value is needed, for example as a key in a dictionary.
-
-   .. index:: single: integer division
-
-integer division
-   Mathematical division including any remainder.  The result will always be a
-   float.  For example, the expression ``11/4`` evaluates to ``2.75``. Integer
-   division can be forced by using the ``//`` operator instead of the ``/``
-   operator.
-
-   .. index:: single: interactive
-
-interactive
-   Python has an interactive interpreter which means that you can try out things
-   and immediately see their results.  Just launch ``python`` with no arguments
-   (possibly by selecting it from your computer's main menu). It is a very powerful
-   way to test out new ideas or inspect modules and packages (remember
-   ``help(x)``).
-
-   .. index:: single: interpreted
-
-interpreted
-   Python is an interpreted language, as opposed to a compiled one.  This means
-   that the source files can be run directly without first creating an executable
-   which is then run.  Interpreted languages typically have a shorter
-   development/debug cycle than compiled ones, though their programs generally also
-   run more slowly.  See also *interactive*.
-
-   .. index:: single: iterable
-
-iterable
-   A container object capable of returning its members one at a time. Examples of
-   iterables include all sequence types (such as :class:`list`, :class:`str`, and
-   :class:`tuple`) and some non-sequence types like :class:`dict` and :class:`file`
-   and objects of any classes you define with an :meth:`__iter__` or
-   :meth:`__getitem__` method.  Iterables can be used in a :keyword:`for` loop and
-   in many other places where a sequence is needed (:func:`zip`, :func:`map`, ...).
-   When an iterable object is passed as an argument to the builtin function
-   :func:`iter`, it returns an iterator for the object.  This iterator is good for
-   one pass over the set of values.  When using iterables, it is usually not
-   necessary to call :func:`iter` or deal with iterator objects yourself.  The
-   ``for`` statement does that automatically for you, creating a temporary unnamed
-   variable to hold the iterator for the duration of the loop.  See also
-   *iterator*, *sequence*, and *generator*.
-
-   .. index:: single: iterator
-
-iterator
-   An object representing a stream of data.  Repeated calls to the iterator's
-   :meth:`__next__` method return successive items in the stream.  When no more
-   data is available a :exc:`StopIteration` exception is raised instead.  At this
-   point, the iterator object is exhausted and any further calls to its
-   :meth:`__next__` method just raise :exc:`StopIteration` again.  Iterators are
-   required to have an :meth:`__iter__` method that returns the iterator object
-   itself so every iterator is also iterable and may be used in most places where
-   other iterables are accepted.  One notable exception is code that attempts
-   multiple iteration passes.  A container object (such as a :class:`list`)
-   produces a fresh new iterator each time you pass it to the :func:`iter` function
-   or use it in a :keyword:`for` loop.  Attempting this with an iterator will just
-   return the same exhausted iterator object used in the previous iteration pass,
-   making it appear like an empty container.
-
-   .. index:: single: LBYL
-
-LBYL
-   Look before you leap.  This coding style explicitly tests for pre-conditions
-   before making calls or lookups.  This style contrasts with the *EAFP* approach
-   and is characterized by the presence of many :keyword:`if` statements.
-
-   .. index:: single: list comprehension
-
-list comprehension
-   A compact way to process all or a subset of elements in a sequence and return a
-   list with the results.  ``result = ["0x%02x" % x for x in range(256) if x % 2 ==
-   0]`` generates a list of strings containing hex numbers (0x..) that are even and
-   in the range from 0 to 255. The :keyword:`if` clause is optional.  If omitted,
-   all elements in ``range(256)`` are processed.
-
-   .. index:: single: mapping
-
-mapping
-   A container object (such as :class:`dict`) that supports arbitrary key lookups
-   using the special method :meth:`__getitem__`.
-
-   .. index:: single: metaclass
-
-metaclass
-   The class of a class.  Class definitions create a class name, a class
-   dictionary, and a list of base classes.  The metaclass is responsible for taking
-   those three arguments and creating the class.  Most object oriented programming
-   languages provide a default implementation.  What makes Python special is that
-   it is possible to create custom metaclasses.  Most users never need this tool,
-   but when the need arises, metaclasses can provide powerful, elegant solutions.
-   They have been used for logging attribute access, adding thread-safety, tracking
-   object creation, implementing singletons, and many other tasks.
-
-   .. index:: single: mutable
-
-mutable
-   Mutable objects can change their value but keep their :func:`id`. See also
-   *immutable*.
-
-   .. index:: single: namespace
-
-namespace
-   The place where a variable is stored.  Namespaces are implemented as
-   dictionaries.  There are the local, global and builtin namespaces as well as
-   nested namespaces in objects (in methods).  Namespaces support modularity by
-   preventing naming conflicts.  For instance, the functions
-   :func:`__builtin__.open` and :func:`os.open` are distinguished by their
-   namespaces.  Namespaces also aid readability and maintainability by making it
-   clear which module implements a function.  For instance, writing
-   :func:`random.seed` or :func:`itertools.izip` makes it clear that those
-   functions are implemented by the :mod:`random` and :mod:`itertools` modules
-   respectively.
-
-   .. index:: single: nested scope
-
-nested scope
-   The ability to refer to a variable in an enclosing definition.  For instance, a
-   function defined inside another function can refer to variables in the outer
-   function.  Note that nested scopes work only for reference and not for
-   assignment which will always write to the innermost scope.  In contrast, local
-   variables both read and write in the innermost scope.  Likewise, global
-   variables read and write to the global namespace.
-
-   .. index:: single: new-style class
-
-new-style class
-   Any class that inherits from :class:`object`.  This includes all built-in types
-   like :class:`list` and :class:`dict`.  Only new-style classes can use Python's
-   newer, versatile features like :meth:`__slots__`, descriptors, properties,
-   :meth:`__getattribute__`, class methods, and static methods.
-
-   .. index:: single: Python3000
-
-Python3000
-   A mythical python release, not required to be backward compatible, with
-   telepathic interface.
-
-   .. index:: single: __slots__
-
-__slots__
-   A declaration inside a *new-style class* that saves memory by pre-declaring
-   space for instance attributes and eliminating instance dictionaries.  Though
-   popular, the technique is somewhat tricky to get right and is best reserved for
-   rare cases where there are large numbers of instances in a memory-critical
-   application.
-
-   .. index:: single: sequence
-
-sequence
-   An *iterable* which supports efficient element access using integer indices via
-   the :meth:`__getitem__` and :meth:`__len__` special methods.  Some built-in
-   sequence types are :class:`list`, :class:`str`, :class:`tuple`, and
-   :class:`unicode`. Note that :class:`dict` also supports :meth:`__getitem__` and
-   :meth:`__len__`, but is considered a mapping rather than a sequence because the
-   lookups use arbitrary *immutable* keys rather than integers.
-
-   .. index:: single: Zen of Python
-
-Zen of Python
-   Listing of Python design principles and philosophies that are helpful in
-   understanding and using the language.  The listing can be found by typing
-   "``import this``" at the interactive prompt.
