Feature CCS "unknown" or "unexpected"

I'm not sure if something like this exists already, as I couldn't find it by searching and the mafia wiki page for CCS seems a little underdeveloped, but I would find it immensely useful for an [ unknown ] predicate in CCS. I imagine this would be fairly simple to implement - handle any monster that mafia doesn't know - and would allow automated accounts to step up their game or alert the user or whatever.

Even more awesome would be [ unexpected ] which would trigger on any monster appearing out of its zone but with a few caveats:

1. any unknown monster would trigger this, unless [ unknown ] is stated in the CCS separately.
2. any arrow'd monster would be exempt
3. teleportitis would render this null, except for potentially (1).

Though I imagine this would be a lot tougher to implement.

I've also been told that CCS can match on zone names and other things as well, but is there a concise thread somewhere detailing how precedence works for collisions? Or even just list that mentions all the various things that work?

Hola wrote clear commit notes when he added the ability to match $item[], $phylum[] and $element[], in r10815 and r10824.
