Mainly because it's *not* basic Perl. It's a subtle effect that isn't obvious. If the OP included the ampersands without commenting, it would be reasonable for a maintainer to remove them, not knowing the effect they have on speed. And as you are fond of pointing out, not everyone who programs is a good programmer, right?

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.

The effect I was referring to was the increase in speed, and not the visibility of @_. This effect is not documented in perlsub, as far as I have been able to determine.	[reply]
