I generally agree and I add a _Static_assert but I want to mention the
usefulness is a bit limited in this case, since we have a bitfield inside a
union. So it only really helps if you manage to exceed the size of mask.

There really is no way around the stuff I put in the selftests.

I could of course try to make that code _Static_asserts but it will not be
pretty.
