You could if you were implementing a pointer/int pair, which is exactly what
that data type does.
This reinforces my point. I believe that you could use Brian's framework to
create a typedef consisting of a compound pointer/bitfield representation
and call it something similar. Regardless of its name it's still going to
have a tuple-like or component-like interface to access the pointer and the
bitfield. (Brian, please correct me if I'm wrong).
I would think that the point of creating this particular data type
(pointer_plus_bits) was to emphasize the pointer aspect and less so the
"pair". If you really want a pointer/int tuple, then create one. If you want
a pointer plus some bits, then I think this would be the place to look--but
only if it worked more or less like a pointer.
