nSo far we have used classes and objects to represent generalized abstractions.
nWe learned how to enable these abstractions to be used in the same contexts as built-in types.
nWe learned what design tradeoffs to make to keep our abstractions as efficient as possible.
nBut, even though we were using objects, we were not using object-oriented programming. We were simply one step closer by understanding the syntax of classes and objects.
nOur abstractions were limited to stand alone
classes.
