this has annoyed Bjarne Stroustrup, as well.  see his book The Design and
Evolution of C++.  consider that published interfaces can be inherited, but
private parts cannot.  it would make sense to inherit from a class that had
the published interface into a class with the private parts necessary to
implement it.  few do this, however.
