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

your original suggestion of putting superclasses "in charge" of their
subclasses.
