Re: Referencing the locals

Hi. You'll get a better understanding of this by taking a look on Variables and Scoping tutorials, and I definitely recommend this article too.

P.S.: Later on, I noticed scoping rules are not the key point here. Yet the reading I mentioned helps.

Note that this isn't an issue of scoping, and none of those links discuss symbolic references.

$ perl -le '$x=2; my $x=4; print ${x}, ${"x"}'

My bad. It's just that I saw the term local variables associated to lexical variables, and ended up focusing on that. I'm sorry.

No worries, and thanks for editing your node! In the context of the question, the difference between lexical and package variables is relevant, which those tutorials do cover.
