I doubt you would even notice those empty loops. But keep it this way if
you want. If you assign mask, you can use it for other purposes as
well.

Same for masks.

It is a very elegant solution, though, since you use each bit
separately. I would use mask myself in such kind of problem; it can be
added as well, if needed, though, no problem.

As said, no problem.
