Hi Calvin,

If you want, you can also grab the reference implementation from my blog: http://ironfroggy-code.blogspot.com/

This reference implementation is broken. It doesn't pass the following test, for example:

 class A(object):
     __metaclass__ = autosuper
     def f(self):
         if type(self) is B:
             return "we've got a B"
         else:
             return "oups"

 class B(A):
     def f(self):
         return Super.f()

 assert B().f() == "we've got a B"

I don't honestly think that you can easily fix the implementation to pass this test, but I'm ready to check proposed fixes and write tests for them. If there is really no working implementation yet then it shouldn't have been a PEP posted on python-dev in the first place, IMHO (and the discussion shouldn't go on on python-dev either).

A bientot,

Armin.
