> "OOP to me means only messaging, local retention and protection and hiding of state-process, and extreme late-binding of all things. It can be done in Smalltalk and in LISP. There are possibly other systems in which this is possible, but I’m not aware of them. "
Excellent quote. He correctly omits types from his description, yet OOP is typically taught (especially in school) as a system of types. We're being dishonest when we say "object oriented" when we really mean "class oriented".
It's not just in schools. It's more a consequence of the fact that the vast majority of mainstream languages use the Nygaard model class-oriented incarnation of OOP, rather than Kay's model of messaging.
