Can I Get It to Go Faster?

• By default, List::Compare sorts the lists its methods returns.

• You can get a small speed boost if you pass the Unsorted option to the constructor.

      $lcu = List::Compare->new('-u', \@Llist, \@Rlist);

  or

      $lcu = List::Compare->new('--unsorted', \@Llist, \@Rlist);
  
      @intersection = $lcu->get_intersection;
      # @intersection will not be sorted
