As was once pointed out to me some years ago, when I wrote something similar, a.f() is not just a shortcut for A.f(a) [a.__class__.f(a)]. The latter only looks for f in the class A namespace while the former also looks in superclass namespaces. The 'magical' part of accessing functions via instances is the implementation of dynamic inheritance. Terry Jan Reedy -- http://mail.python.org/mailman/listinfo/python-list
