Actually, one can specify a physical representation of
My_Integer_Type that is different from Integer's. Also,
one may supplant or subtract "primitives".

When I do not need type substitution, e.g. because all
objects do their work well, and locally, then the solution is
to adapt notions of type to the solution at hand as necessary,
and if necessary at all, rather than to force working solutions
to match orthodox notions of type. Nothing wrong with the
latter, globally.
