super is a lexically scoped concept.  You cant ask the instance for it
since it's value is different depending on in which it is needed Just
as:

        class foo(bar):
              def __repr__(self):
                  return self.__class__.__repr__(self)

would get you into an infinite loop, while:

        class foo(bar):
              def __repr__(self):
                  return bar.__repr__(self)

wont.  Now, dont go thinking that

        class foo(bar):
              def __repr__(self):
                  return self.__class__.__base__[0].__repr__(self)

will do you any good either ;) Because it wont!
