Message 75322 - Python tracker

The attached example works in the __add__ and __getattribute__ cases on
CPython, but fails in the __getattr__ case.  All three cases work as the
semantics say they should on Jython, IronPython and PyPy.  It's
admittedly an obscure use case. 

There is no reason that __getattr__ should behave differently.  The
behavior of __add__ and __getattribute__ is the "correct" one, according
to the rule that special methods are bound (with __get__) before they
are called.
