We've already got them packed in with other bit-fields from the expression bits, so I think it's reasonable to continue the pattern of using bit-fields (that way we don't accidentally end up with padding between the unnamed bits at the start and the named bits in this object). I think adding some assertions would not be a bad idea as a follow-up.
