      Ahh, I just caught this too, after it was quoted by someone else.

      There's no *qw* in there. It's just a simple list.

      Please learn that:

      ( ... )

      is different in many ways from:

      qw( ... )

      These are TWO DIFFERENT constructs. qw() is a "quoted word" list:

      qw(fred barney betty wilma dino)

      is the same as:

      ('fred', 'barney', 'betty', 'wilma', 'dino')

      without all the extra quotes and commas.

      Now go back and re-read what I said. You can't have comments
      inside qw(). You can *certainly* have them in insignificant places
      inside (), as well as commas (separating and trailing).
