If I see @n[$i] I get very worried.

I don't. It's about time we got rid of that warning. It's going to be the right syntax in perl6, it's doing the right thing in perl5, and considering that:

@n[$i,$j,$k,$l] @n[$i,$j,$k] @n[$i,$j]
return 4, 3, and 2 element slices - the use of @n[$i] isn't unnatural at all. Its a one element slice. And what does a slice in scalar context return? It's last element. Which, obviously, is $n[$i].

So, I think in this case that Perl should act perlish, and shut up and DWIM (which it is doing already). And not whine and pretent to be Java or Python.

    I don't.

    Perhaps you should. Here's one example (paraphrased from real life) of how it can get ugly...

    #!/usr/bin/perl $\=$/; @n[0] = localtime; $n[1] = localtime; print for @n;

    -sauoq
