  Check in the patch proposed by Ben Hayden (benjhayden) for issue
  #1550: help('modules') broken by several 3rd party libraries.

  Tested with Python build: trunk:54235:59936M -- the reported error
  occurs with Django installed (or with any __init__.py present on
  the path that raises an exception), and such errors indeed go away
  when this change is applied.

  Back out r59931 - test_ctypes fails with it.

  As discussed in issue 1700288:
  ctypes takes some liberties when creating python types: it modifies the types'
  __dict__ directly, bypassing all the machinery of type objects which deal with
  special methods.  And this broke recent optimisations of method lookup.
  Now we try to modify the type with more "official" functions.

  Re-apply patch #1700288 (first applied in r59931, rolled back in r59940)
  now that ctypes uses a more supported method to create types:

  Method cache optimization, by Armin Rigo, ported to 2.6 by Kevin Jacobs.

  ?Why did my tests not notice this before?
  Slots inheritance is very different from OO inheritance.
  This code lead to infinite recursion on classes derived from StructType.

  Added new an better structseq representation. E.g. repr(time.gmtime(0)) now returns 'time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)' instead of '(1970, 1, 1, 0, 0, 0, 3, 1, 0)'. The feature is part of #1816: sys.flags

  Now that I've learnt about structseq objects I felt like converting sys.float_info to a structseq. It's
  readonly and help(sys.float_info) explains the attributes nicely.

  Added more comments to the new structseq repr code and implemented several of Neal's suggestions.

-   Combine ``'b'`` with ``'r'``, ``'w'``, or ``'a'``, for binary
-   mode, e.g., ``'rb'`` to open a file for reading in binary mode.
-   Modes ``'r+'``, ``'w+'`` and ``'a+'`` open the file for updating (note
-   that ``'w+'`` truncates the file).
+   The most commonly-used values of *mode* are ``'r'`` for reading, ``'w'`` for
+   writing (truncating the file if it already exists), and ``'a'`` for appending
+   (which on *some* Unix systems means that *all* writes append to the end of the
+   file regardless of the current seek position).  If *mode* is omitted, it
+   defaults to ``'r'``.  The default is to use text mode, which may convert
+   ``'\n'`` characters to a platform-specific representation on writing and back
+   on reading.  Thus, when opening a binary file, you should append ``'b'`` to
+   the *mode* value to open the file in binary mode, which will improve
+   portability.  (Appending ``'b'`` is useful even on systems that don't treat
+   binary and text files differently, where it serves as documentation.)  See below
+   for more possible values of *mode*.
 
    Python distinguishes between files opened in binary and text modes, even
    when the underlying operating system doesn't.  Files opened in binary
