Determining the class object to use '''''''''''''''''''''''''''''''''''

The exact mechanism for associating the method with the defining class is not specified in this PEP, and should be chosen for maximum performance. For CPython, it is suggested that the class instance be held in a C-level variable on the function object which is bound to one of NULL (not part of a class), PyNone (static method) or a class object (instance or class method). Another open issue here: is the decorated class used, or the undecorated class?

Sorry I've taken so long to get back to you about this - had email problems.

I'm not sure what you're getting at here - are you referring to the decorators for classes PEP? In that case, the decorator is applied after the class is constructed, so it would be the undecorated class.

Are class decorators going to update the MRO? I see nothing about that in PEP 3129, so using the undecorated class would match the current super(cls, self) behaviour.
