Fantastic post. It's information like this that keeps me coming back to Perl Monks.
in reply to Shift, Pop, Unshift and Push with Impunity!
I'm fascinated at the internal aspects to Perl. I'd be interested in seeing a (somewhat) regular post from the experts in this area (merlyn?) to give some insight on different perl internals. Perhaps some insight into not only what it is, but why. We could even set up a question submission (a la, "ask slashdot") and send the higher-voted questions to the saints.
What do the rest of you think?
