`Loop counter variables`

But surprisingly, this very weird example actually demonstrates a red flag
And a really nice one
A variable whose only job is to track the number of iterations through a loop
This is a good example
- Because it's obvious that it isn't always the wrong thing to do
- For instance:

        for my $item (@items) {
          $counter++;
          print "$counter: $item\n";
        }
