--- Comment #1 from Timothee Cour <timothee.cour2 at gmail.com> ---
IIRC: was triggered from dfmt by an input of type `immutable(short)` looks like
logic breaks when input is immutable?


Num abs(Num)(Num x) @safe pure nothrow
if ((is(typeof(Num.init >= 0)) && is(typeof(-Num.init)) ||
    (is(Num == short) || is(Num == byte))) &&
    !(is(Num* : const(ifloat*)) || is(Num* : const(idouble*))
    || is(Num* : const(ireal*))))
{
    static if (isFloatingPoint!(Num))
        return fabs(x);
    else
    {
        static if (is(Num == short) || is(Num == byte))
            return x >= 0 ? x : cast(Num) -int(x);
        else
            return x >= 0 ? x : -x;
    }
}
