I understand your concern, still, in my eyes COW is just another
application of the handle/body pattern and thus not /that/ far
away from the scope of this submission.

Whether a single policy-based can-do-whatever-pointer is really
what we want is a different story.

    However, it's implementation can be tricky, and with many pitfalls
    (especially regarding memory management).

    template<typename T> void dispose_func(void* ptr)
    { delete static_cast<T*>(ptr); }
    // use void(*)(void*) to this thing for freeing the shared context
    // and the instance
