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.
