And, again, what makes `interactive' special here?  Any time we
introduce something new on the language level, of course you can't use
that in older Emacs versions.

(Stefan K's macro makes it trivial to use in out-of-tree packages,
though.)

No, you can add any predicates you want.  But not via `interactive'.

Better names are welcome.
