Love the example!
So polymorphism is basically totally programmer dependent. There seems to be nothing "in" the language designed to specifically make polymorphism possible (or not).
It looks like I could say that "polymorphism" in OOP is the considered and judicious use of inheritance to permit same-named methods to respond as appropriate for its context. (or something close to that)
thanks
