I tried to rework the functions to use bitwise operations, but
it was difficult to figure out the correct logic. I decided
that it's not worth the hassle, so I just changed the value
storage from `bool[3]` to `ubyte`. Now it works much more like
your version.

I did a little reading, so now I understand what it means when
you have `&= 7`. But I want to ask, is this faster than `%= 8`?
If not, I would like to change it to the latter for readability.
`%=8` will be codegened using slower intructions w/o optimz
enabled but with `&=7` you directly get the right instruction,
which does not involves integer division. See
