There are no cast operators that allow you to cast a vector (or matrix, for that matter) element-wise. For example:

operator int4(uint4 v)
    return int4(int(v.x), int(v.y), int(v.z), int(v.w));

Metal supports these; I think they would be a useful utility to add to the standard library.

HLSL doesn't have these; I'm not sure we should either.
