Re: The CORRECT thinking behind the {}s and the ()s.

I wouldn't say there was a trick to remembering them, it's just a matter of remembering.

Either learn them or just use (), and if you need a reference, reference the hash or array you created with a backslash.

When the time comes, and you can't be bothered doing that any more then start using {} or [ ] as desired.

I know when I started writing Perl I didn't use {} or [ ] much, but used plenty of \% or \@.

Just to confuse things more... :) Either learn them or just use (), and if you need a reference, reference the hash or array you created with a backslash.
