There is a comment in the other thread Missing $ on loop variable? about how shell programmers might forget that in Perl the "$" is required.

    That's an interesting idea. Perhaps that's it after all.

    I might be mis-remembering: perhaps it was the @ on the array that was optional? I'm pretty sure it was one of them, but it's been a long time since I've had Perl 4 on my computer.Update It is neither. I must have been thinking of what japhy says.

      The @ and % are optional for a lot of functions: push, pop, shift, unshift, splice, keys, values, each.
