Make functional.partial() more closely match the spec by emulating some useful features of regular functions:
* Made weak referencable. * Allow attribute access so a user can set __name__, __doc__, etc.

\class{partial} objects are like \class{function} objects in that they are
|
||||
callable, weak referencable, and can have attributes. There are some
|
||||
important differences. For instance, the \member{__name__} and
|
||||
\member{__doc__} attributes are not created automatically. Also,
|
||||
\class{partial} objects defined in classes behave like static methods and
|
||||
do not transform into bound methods during instance attribute look-up.
