    Sure, the end result is that $data only holds the unique values: From this:
    my $data = [ { 'type' => 'Paper' }, { 'type' => 'Paper' }, { 'type' => 'Plastic' }, { 'type' => 'Plastic' }, { 'type' => 'Plastic' }, { 'type' => 'Plastic' }, { 'type' => 'Cotton' }, { 'type' => 'Cotton' }, { 'type' => 'Cotton' }, { 'type' => 'Cotton' }, { 'type' => 'Cotton' }, { 'type' => 'Paper' }, { 'type' => 'Paper' }, { 'type' => 'Paper' }, { 'type' => 'Paper' }, { 'type' => 'Paper' }, ];
    To that:
    $data = [ { 'type' => 'Paper' }, { 'type' => 'Plastic' }, { 'type' => 'Cotton' }, ];
      hdb's code does exactly that, albeit sorted.
