C++, Java and D follows Simula. Simula's protection levels were added in the 70s: hidden, protected and hidden protected, but the defining characteristics is class inheritance, virtual functions and coroutines. I didn't know those had been added. If it had them from the start, would that make encapsulation another defining characteristic? | |||

I would say encapsulation has more to do with scaling up and evolving, as well as reliability (e.g. actors). But I guess you can say that OO features span a space where encapsulation is one dimension. | |||

Right, but Python programmers are expected to prepend private members with '_'. >I would say encapsulation has more to do with scaling up and evolving, as well as reliability (e.g. actors). Then it is natural to expect the feature would apply to the class level (if we are talking about class-based OOP)? Really, I'm yet to meet a D user that wouldn't be surprised 'private' is module-level. And the 'friend' story rarely impresses them. The reply is always: "Ok, 'friend' breaks OOP principles. Is D better because it breaks OOP in its own way?" | |||

Why not prepare well written DIP with examples from other languages and to ask some experienced core developer to have a look at it?
