vec = overloaded vector type of size 3.

What I meant to write:
vec v = vec(0, 0, 3);

What I actually wrote:
vec v = (0, 0, 3);

Result:
vec v = 3; // as in vec(3, 3, 3);

It was quite nasty. Considering D doesn't allow statements like 3; I don't see
why it isn't an error to do it when using the comma operator in an assignment.
It literally just throws away everything with no side effect.

Or make it easy and just remove the comma operator completely in its current
form.
