Are These Items Found in Any Lists?

• Challenge: Sometimes we want to know whether one or more items were found in any of several lists

• Response: Two new methods which return Boolean(-ish) values

  •     $found = $lcm->is_member_any('abel');
        # $found will be:  1

  •     $memb_hash_ref = $lcm->are_members_any(
                 [ qw| abel baker fargo hilton zebra | ] );
    
        # $memb_hash_ref will be:
    
        {
             abel     => 1,
             baker    => 1,
             fargo    => 1,
             hilton   => 1,
             zebra    => 0,
        };
