Yep, I try with opCast and to! not works yet. At least, I can do now, 
things like :

auto v2d = Vector!(doble, 2) (1, 1);
auto v = cast(Vector!(float, 4)) v2d;
assert (v[0] == 1);
assert (v[1] == 1);
assert (v[2] == 0);
assert (v[3] == 0);

PD: Yep, I'm learning making a small lib to work with Vectors, 
Quaternions and squared Matrix...
