This had already been tried with the effect that arithmetic operations
were no longer valid, to wit, X / 10, X mod 10. I don't know if this
is just a compiler issue or whether this is a more fundamental
problem. (If I remember correctly, the 'use' clause did not work
either).
David Hoos mentioned that: Interface.Unsigned_32 would be the way to
go. I haven't tried this yet.
