Sorry for being unclear, I was referring to the member function pointers
and the fact that currently the binding is restricted to raw pointers,
ie it is

        template <typename OBJECT, typename METHOD>
        callback(OBJECT* object, METHOD method) ...

rather than

        template <typename PTR, typename METHOD>
        callback(PTR ptr, METHOD method) ...

Assuming smart pointers that supported operator->*, we have a higher
degree of openness and versatility for no extra cost.

Whether the class should support this inside or outside I leave as a
separate issue :->
