Add nested scopes spec to appendix.
Add new opcodes LOAD_CLOSURE, LOAD_DEREF, STORE_DEREF, MAKE_CLOSURE to
docs for dis module.
Add docs for new function and code members in Sec. 3 of ref manual.
They're present regardless of whether nested scopes are used.
Remove description of default argument hack from Sec. 7 of the ref
manual and refer the reader to the appendix.

Because of Python's two-scope philosophy, a local -function defined in this way does not have access to the local -variables of the function that contains its definition; the same rule -applies to functions defined by a lambda form. A standard trick to -pass selected local variables into a locally defined function is to -use default argument values, like this: - -\begin{verbatim} -# Return a function that returns its argument incremented by 'n' -def make_incrementer(n): - def increment(x, n=n): - return x+n - return increment - -add1 = make_incrementer(1) -print add1(3) # This prints '4' -\end{verbatim} +passed around. The semantics of name resolution in the nested +function will change in Python 2.2. See the appendix for a +description of the new semantics. \section{Class definitions\label{class}} \indexii{class}{definition} |
