// key, then there is a big chance it is a new key. But just to be
// sure, we also check out key index if it does not already exist.
// Finally, we just delegate to OnInsert. In effect, we're
// converting OnSet to OnInsert where needed. Ideally, the base
// implementation would have done this for.
