Unfortunately, this breaks down once you get to templates:

    template <typename T>
    class Foo : superable<typename Bar<T>::type> {
        // the base is dependant, so you still have to
        typedef typename superable<typename Bar<T>::type>::super super;
    };

So IMHO the question is whether

    class C : boost::superable<B>
    {

is really superior to

    class C : B
    {
        typedef B super;

and I'd have to say no.
