Yea, which makes sense -- any code that needs both should _know_ it needs both.

Actually, abs itself is not really a problem here as std.math.abs should work 
for just about any integer-like type, the real places where this will matter are 
stuff like greatest common divisor or least common multiple ...

I had some concern about generic numerical code that doesn't know the type it's 
operating on, but on the other hand such code probably shouldn't be calling a 
specific implementation of (e.g.) abs, gdc or whatever.
