The problem is that the function needs to return
int, but given two uints, their difference may be
greater than int.max, so simply subtracting them
will not work. So the best I can come up with is:
Should of course be:
int compare2(uint x, int y)
{
return (x int.max) ? 1 : (cast(int)x - y);
}

I would like that, if it would be implemented along this line:
/// Returns -1 if a b, 0 if they
Of course without the ! after opCmp in the several cases.
