It is another incarnation of special methods being looked up on the class,
not the instance. This was always the behavior with new-style classes, see
the thread at

http://mail.python.org/pipermail/python-3000/2007-March/006261.html

for a previous discussion.

I think we should tackle this issue now and make sure the decided resolution
is consistently applied throughout Python.

two, excepting that thou then proceed to four. Tabs are right out.
