Re: dereferencing question

[swl]

The @ and % sigils indicate you want a list and not a scalar.

If you use an array directly then you get a warning. I'm not sure why it does not appear for array derefs.

perl -E"use warnings; my @array = (1..3); print @array[2];"
Scalar value @array[2] better written as $array[2] at -e line 1.
