"Good" OOP and "bad" OOP. There's just no difference. And quite frankly, if the only difference between their "getX" and a symmetrical message passing pattern that retrieves a copy of an attribute is the implementation details then... what?

So much of "Good OO" seems to be prescribing people's mental models and not their actual practices. Seems somewhat odd to me, since most of the models are indistinguishable from one another in practice.
