No, it's not needed. Just like `use strict` and `my` aren't "needed". But if your code happens to have a `$main::x`, you'll be thankful you used `local`. Abigail	[reply] [d/l] [select]

Er, sarcasm aside, the reason I asked was because the documentation suggested to me that they were automatically localized. --- demerphq my friends call me, usually because I'm late....	[reply]

`$x = $y = "apple"; "orange" =~ /(.*)(?{$x = $^N; local $y = $^N})/; print "$x\n$y\n"; __END__ orange apple` [download] If all variables would be automatically localized, it would be hard to pass any information from the regex back to the program. I can't find something in the documentation that suggests variables are automatically localized. Abigail	[reply] [d/l]
