[rules-users] list conatins objects from another list

[Wolfgang Laun]

You could do
   $s: String() from cids
   eval( pids.contains( $s ) )
but this would fire for every element of cids occurring in pids.

If you'd like to have a single activation if the intersection of both sets
isn't the empty set, you'll have to write a function deciding just that,
and call it:

   eval( intersectionNotEmpty( cids, pids ) )
