Re^7: Using an "outer" lexical in a sub?

The file-scoping is annoying I guess, but sort of in line with lexical scoping rules. And I haven't used perl 5.005 in ages.

You have 2 files that access one package and you introduce synchronization issues.

How does that happen? I though our() just made package variables available without too much fuss.

You say "package Foo" in two different files. :-) As I said, this should be very rare. But sometimes you want to add or modify functionality in a package someone else wrote. (I've done this several times in Ruby where I'm changing core classes.) However there is a more common variation of the same thing. If you take a module and refactor it by using AutoLoader, then our variables are not visible in the autoloaded subroutines, but use vars would be.	[reply]
