Tom, I personally would focus on the ability to take two classes (from an OOP approach) and inherit from them (this does, though, require multiple inheritance to be clearest cut). To stay in the abstract, an OOP programmer who has implemented a sports car class, and a pickup class, should only take a short time to produce a sound sports pickup class (descended from both), whilst this should be more tricky for a procedural programmer. Making life hard for the OOP programmer might be in changing a class to something completely different, although that is artificial and is probably no harder for OOP. Howard.
