How is this a problem? There is no ambiguity between the global scope and
the local from within foo.

>From within foo C is accessed from the global scope having not found it as a
local. Once you have C C.x is just one step away. 

Variable self is local to function foo since it was passed in as a parameter
from the method which wraps it. 

Variable self refers to a class instance which contains a dictionary.
Variable x is absent from the instance dictionary so the class
self.__class__ is referenced, again from local scope to find x. If it
wasn't found there the superclasses would have been searched before
throwing an attribute error.

It seems to me, you are confusing instance creation with class creation.
