Only, and let me stress that, ONLY, when your classes inherit from
exactly *one* superclass, and you mandate that every class that
inherits from any of your classes ALSO inherits from exactly one
superclass. If *any* class ever inherits from one of your classes and
also something else, hard-coded superclass names become straight-up
wrong.

Have you put code into your classes to prevent anyone from ever
multiply inheriting?
