Okay, then. Since you started this discussion from the topic of multiple inheritance I was under the impression that you were talking about using inheritance to construct Rationals from integers and sets. Evidently that is not so, and you've been talking about composition all along, in which case I have no idea how any of this relates to your original suggestion of putting superclasses "in charge" of their subclasses. -- http://mail.python.org/mailman/listinfo/python-list
