	If a signal (rather than a constant number) is used on the right side of the comparison with ''anything'', it is implicitly excluded from the set of signals that ''anything'' checks, so the signal is not matched against itself.

The value for copper plates will rapidly (but not instantly) shoot upward. (The rate at which it climbs is determined by the current tick rate.)
