It's a subtle effect that isn't obvious.well, it's documented in the beginning of perlsub.pod. i want to program assuming my co-workers/successors have at least read the common perldoc-pages. i don't want to comment things that are already documented in the documentation for perl itself. what i *would* docunment in a case like this is *why* i do this. so instead of saying &foo; # give current @_ to foo. i'd say &foo; # foo needs @_ because ... then any programmer stumbling over this code would know why or have to read perlsub.
