My guess is that one cannot swap between different types (void * and
intptr_t, being a pointer type and an integer type, respectively), but I
would be inclined to think that char * and const char * do not differ in
type, only in qualifier, so perhaps one could, in that case.
However, I still have to consign this technique to the reject pile of those
that do not make the grade.
