Note that there is no requirement at all that this work,
but it is not surprising to find that it would work
(accidentally? is it documented, I am not sure that it
is properly documented for GNAT either come to think
about it) since it is an obvious way of implementing
things.

All the more reason for the ARG to insist on it.

There are issues of what types it can be applied to. Shift
operations applied for example to non-binary modular types
are quite a puzzle.

In GNAT, we allow shifts to be applied to any signed or
binary unsigned integer type whose size is 8, 16, 32, or
64 (i.e. natural machine sizes for which shifts make
sense).

It would be interesting to know what restrictions other
compilers impose on this usage.
