An Alternative Interface

• Response: David H. Adler suggested passing a single hash reference with named arguments:

      @complement = get_complement( {
          lists    => [ \@Al, \@Bob, \@Carmen, \@Don, \@Ed ],
          item     => 3,
          unsorted => 1,
      } );
  
      $LR = is_LsubsetR( {
          lists    => [ \@Al, \@Bob, \@Carmen, \@Don, \@Ed ],
          pair     => [2,3],
      } );
      
      $memb_hash_ref = are_members_which( {
          lists    => [ \@Al, \@Bob, \@Carmen, \@Don, \@Ed ],
          items    => [ qw| abel baker fargo hilton zebra | ],
      } );

• More verbose, but more self-documenting.

• The order in which arguments are passed no longer matters, but you have to get the names of the keys right.

• Now available for both List::Compare and List::Compare::Functional. See documentation for version 0.29 or later.
