Given that p.we.x seems to always return the same object (since the
hashes, which which appear to be ids, are the same), an __eq__ method
(which gets called in preference to __cmp__), possibly inherited, that
always return False is the only thing I can think of. (Hence Martin's
question, I presume). I have no idea, however, how porting could make
that happen.
