I'm not sure I agree.

In Ruby, this is true, because of how instance variables work.

In C++, if I inherit, I need only know about my parent class's protected
methods and data members; private methods/data members are an
implementation detail that I need not worry about.  C++ and Ruby are
very different languages, though, with very different requirements on
the user.
