To use an old English idiom, I think you are putting the cart before the
horse [as did Modern C++ Design, IMNSHO]

Resource protection is a useful concept, and pointers are simply another
resource that needs protecting. It makes little sense to dereference a
mutex, for instance. This is one of the defining concepts of a pointer.

Rather, I think if we seek a generic implementation the 'base' concept
is resource protection, and smart pointers are a refinement of this
