Actually, Adam's suggestion on how things should work is precisely how C
works (except it trails off at int).
a = b + c;
if b and c are both a byte, and a is a byte, the result is unpromoted.
If a is a short, the result is promoted. I know the mechanism is
completely different than what Adam was suggesting, but the end result
is precisely the same.
Consider:
void fun(byte);
void fun(int);
fun(b + c);
Under the new rule, this code (and much more) would silently change
behavior. How would that get fixed?
Not under my suggested implementation:
If more than one use is possible (i.e. - overloading), use the largest one
applicable.
