Does that mean you disagree with the warning?

It's meant to enforce style, but I agree with the style being enforced, and it can detect typos (refactoros?).

Or are you like the ancient Greek who didn't consider 1 not to be a proper number, and you don't consider one-element lists to be proper lists?

Do you honestly think in terms of lists when you do $a[4]? I don't.

But sometimes, the slice one wants is just one element.

Of course. I didn't mean to imply otherwise. Note that Perl doesn't warn when you don't use a constant. 

$ perl -wle'my @a = qw( a b c ); my @i = 2; print @a[@i]'
c

In fact, using $ wouldn't work in that situation. 

$ perl -wle'my @a = qw( a b c ); my @i = 2; print $a[@i]'
b

I can't figure out what you think I was saying, but hopefully this clears it up.
