Darn.  I knew Python 2.3 had tightened the rules on assignment to 
__class__, but I forgot that this made a difference for metaclasses.

Well, there goes my plan for making it possible to cleanly use bindings in 
any class regardless of metaclass.  :(  I think there's probably another 
way to do it, but it'll take some research.  In the meantime, I'll change 
the above to work a little differently.
