I'm confused. Why do you want this? Isn't `byte offset` here is just `type offset * sizeof type`?
While I'm not the requester, I think the types that [comment:2 Mathnerd314 proposes] have two advantages:
* They relieve the user from doing the byte offset computation. Then what does that `Int# {-byte offset-}` parameter mean?
