There's never been a guarantee that it would use destructive splicing
(it's just allowed to), and I generally dislike destructive operations,
so I'd rather not go through extra trouble to support what I tend to see
as a misfeature.

So aliasing ,. to ,@ is OK, but making it work destructively is not.
