Methods of Python functions compare equal if the functions are equal and if __self__ is equal:

>>> class X:
...     def __eq__(self, other): return True
...     def meth(self): pass
>>> X().meth == X().meth
True

This is because X() == X() even though X() is not X().

For extension types, we get instead:

>>> [].append == [].append
False

This is because comparison is done with "is" instead of "==". This is a needless difference.
