The problem there is that while the words are right, I don't know of
any case where those two examples are implemented as the words imply.

    class stack : public ADT {};

What goes in the ADT base class that's useful?

Similarly, the library isn't written like this:

    class stl_library {
        stack stack_;
    };

Since the usual OO version of "HAS-A" doesn't work for libraries and types.
