From Alan Kay, the inventor of Object-oriented programming:
> 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.[1]
Agreed - I actually wrote a post about this myself (in the context of comparing Java to Python)[1].
I'm just pointing out how ridiculous it is that the actual father of object-oriented programming thinks that the only object-oriented languages are two which don't even fit this "new" definition!
