Also getting the absolute value of some signed variable
need to return a different type or doesn't work correct for all

E.g. "ubyte abs(byte)" - this functions which can't even use a 
template,
or has anybody a good idea ho to express "unsigned T abs(T)(T 
x)"?

import std.traits : Unsigned;

Unsigned!T abs(T)(T x) { /+ magic... +/ }
