One useful case for me:

static Mat4 transform()(const auto ref Vec3 pos, const auto ref Vec3  
scale, const auto ref Quat rot)
{
     Mat4 m = Mat4(rot.matrix, 1);

     m.m00 *= scale.x;
     m.m01 *= scale.x;
     m.m02 *= scale.x;

     m.m10 *= scale.y;
     m.m11 *= scale.y;
     m.m12 *= scale.y;

     m.m20 *= scale.z;
     m.m21 *= scale.z;
     m.m22 *= scale.z;

     m.m30 = pos.x;
     m.m31 = pos.y;
     m.m32 = pos.z;

     return m;
}

Currently, my choices are template bloat, or pointless copying.
