[New-bugs-announce] [issue3787] Make PyInstanceMethod_Type available or remove it

[Christian Heimes]

New submission from Christian Heimes <lists at cheimes.de>:

A long time ago I added the PyInstanceMethod_Type in r59469. It's a
wrapper that turns every function including PyCFunctions into a bindable
function.

class Example:
    id = instancemethod(id)

Example().id()

Without instancemethod the builtin function is not called with 'self' as
first argument.

The code is in the core for a long time but it has neither been used and
unit tested nor was it exposed yet. The feature was requested by the
Pyrex and Cython developers. The feature should either be removed or
exposed somehow. 

I know it's very late in the release cycle but I feel uncomfortable with
code that has no tests. If you don't want to expose it to the user but
only to C extension writers I'll come up with another plan. For example
I could add the type to the testcapi module and test it there.
