What If I Already Have Seen-Hashes?

• Challenge: Sometimes we've already computed seen-hashes.

      %seenAl =  ( abel   => 2, baker  => 1, camera => 1, 
                   delta  => 1, edward => 1, fargo  => 1,
                   golfer => 1                            );
  
      %seenBob = (              baker  => 1, camera => 1, 
                   delta  => 2, edward => 1, fargo  => 1, 
                   golfer => 1, hilton => 1               );

  Since List::Compare internally transforms lists into seen-hashes, why can't we just pass the seen-hashes directly?

• Response: Now we can.

      $lcsh = List::Compare->new(\%seenAl, \%seenBob);
  
      @intersection = $lcsh->get_intersection;
