in reply to Re: (almost) foldlin thread (almost) foldl
There's no sarcasm. What I said should be interpreted literally.
$_ 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 $_ 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.
