The following works in 2.078.1 but stopped working in 2.079.0. Seems to be selecting std.math.abs instead of vec.abs which are both publicly imported in module 'math'.


/../phobos\std\math.d(564): Error: incompatible types for `(x) >= (0)`: `Vector!(float, 3)` and `int`
/../phobos\std\math.d(564): Error: `x` is not of arithmetic type, it is a `Vector!(float, 3)`
\test\main.d(9): Error: template instance `std.math.abs!(Vector!(float, 3))` error instantiating


*******************************************************

// main.d
import math;


void main()
{
    Vector!(float, 3) v;

    auto t = abs(v);
}

*******************************************************

// vec.d
module vec;


struct Vector(T, int size)
{
    T x, y, z;
}

auto abs(T, int size)(auto ref const Vector!(T, size) v)
{
    return v;
}

    import std.math; // order doesn't change error
    import vec;
