Yeah, that's a good point: How do you define a "class 
with/without destructor", when they all derive from Object 
anyways.

Necessarily, Object needs to have a destructor (even if it does 
nothing) for any other sub-class to have them. Or vice versa, if 
Object has no destructor, no subclass can have them?

So is it even possible to separate classes into two different 
groups?
