That's why I don't like the term OO, because it's used to mean "class-oriented", and class-orientation is a vacant theory. Then you get into the "purity" nonsense. If "purely OO" means "purely class-oriented", how is that demonstratively good, or even significant? It's about as pointless as, let's say, defining "pure pizza" to mean not having tomato sauce, and then calling everything else a "hybrid". "Abstraction oriented" is, I think, both meaningful and useful; and as has been pointed out, is bigger than just the idea of inheritance. Mark Lundquist
