The use case is that I want to be able to validate that a class implements all of the abstract methods of all the classes to which it has been registered.

If you're going down that road, would you be willing to write a patch for http://bugs.python.org/issue9731 along the way?

I don't have a programmatic way of discovering that set without asking every class out there.

I agree it would be nice to have a way to ask a class "which ABCs do you implement?" It would be handy for introspection and debugging purposes. -- Daniel Stutzbach
