Are you saying that creating vars named $_[0] (like you did) is better than creating a var named $acc, or did you just not read my post?

    $_[0] is not created, $acc is, hence it is an extra. The rules say "no extra vars", so your post is missing a point. Which means also that your sarcasm of me allegedly not reading your post is undeserved - I did read it.

      There's no sarcasm. What I said should be interpreted literally.

      $_[0] is not created

      It didn't exist before splice(@_, 0, 0, 1) and your equivalent, and it does afterwards. That's the very definition of created.

      (If you're gonna argue that $_[0] did exist, then its $_[$#_] you created.)

      Where splice and my create the variable differs, but both create a new scalar variable.

      The rules say "no extra vars",

      Again, you've created a whole bunch of vars. If you're not subject to your rule, I'm definitely not.
