As of 2.2, C.hello.im_self == None while c.hello.im_self == c.

Presume still same in 2.3.  This is very much an implementation internal
feature and not part of language definition.  (Meaning: can be changed
without notice.)  I believe this is how repr() tells difference.

This sort of question is better asked on comp.lang.python.  It is about
usage of current python rather than development of future python.
