So I don't mind picking this up, but I'd like some guidance. There are
two issues:

1) The CLI. You and Jeff don't seem to have an agreement here, but
frankly, this is the easy part.

2) The internal implementation. Your implementation (enum -> bitfield)
is clever, but Jeff seems to prefer what I suggested (going to a
struct). The latter is quite a bit more work.

If we only care about fixing the original issue, I'll just pickup your
patch, make sure it compiles, and add some tests. I certainly don't
want to do more work than is needed, unless there's  a good reason to
do so.
