Re: Missing $ on loop variable

I guess this must be a bug in that particular sub-version of perl. I don't have a copy of 5.6.1 handy to test it on, and it's even possible that Sun shipped a non-standard version.

Does anyone else remember why there's a special error message for missing $ on loop variable, rather than it just being a generic syntax error?

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

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.	[reply] [d/l]

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