The question is how to interpret value None:
* Always raise TypeError (with changed message)? This is what happen
currently when you set the method to None, this is the most compatible
option.
* Always raise an error, but allow to change it to more appropriate
type (for example AttributeError for __setattr__)?
* Interpret value None the same way as an absent attribute?
What about binary operators (__add__, __eq__, etc)? Should they act as
if they'd returned NotImplemented? Or immediately unconditionally raise
a TypeError?
