Hi All,

PyMethod_GET_CLASS implemented like this:

It looks like Python 3 has wiped out the "im_class" attribute.

For bound methods, renamed to __class__ to be consistent with other 
objects. Unbound methods were eliminated as extra cruft.

A method (unbound) is simply a function accessed as an attribute of a 
class. A function can be a method of 0 to n classes, and 'belongs' to 
none of them.
