  This is why it's a good idea to avoid C-style for loops in most cases in Perl. It's much harder to make a mistake when you rewrite

  for(my $j = 0; $j > @ell_content; ++$j)

  as

  for my $j (0..@#ell_content)

  because you've only got $j there once instead of three times.

    I go one up and avoid the index altogether:

    foreach my $item (@ell_content)

    I've only written one program I can think of in the last year where I needed the index, and I kept feeling like I was looking at the problem wrong.

      I quite agree. This time I really do need the index, tho, and have to use the C-style: I'm having to iterate over items in an array and sometimes doing crazy things like $thing[$j] = foo($thing[$j], $thing[$j+1]); splice @thing, $j+1, 1; next;

        Huh? You're changing the length of an array whilst iterating an index? Isn't that just asking for trouble? Or maybe you are checking for the past-end-of-array condition...
