Re^4: (almost) foldl

in thread (almost) foldl

$_[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.	[reply] [d/l] [select]
