method. Previously, the pre-sizing optimization only applied to
sequence arguments.
-\item The unbound methods \method{list.__getitem__()},
+\item The methods \method{list.__getitem__()},
\method{dict.__getitem__()}, and \method{dict.__contains__()} are
are now implemented as \class{method_descriptor} objects rather
than \class{wrapper_descriptor} objects. This form of optimized
access doubles their performance and makes them more suitable for
- use as arguments to functionals: \samp{map(dict.__contains__, mydict)}.
+ use as arguments to functionals:
+ \samp{map(mydict.__getitem__, keylist)}.
