>> You cannot use open F,pop; because there are 3 args coming in, not 2.

Huh?!?

The function in question is

sub g{ open(F,'<',$_[1])&&&s($_[0],$a,"e$_[1]",<F>); close F }

On first glance, it looks like you can replace $_1 with pop for a 2-character savings. However, look at where g() is called - &$3($2,$4,$'). There are three scalars in @_, not two. The fact that g() only uses two is irrelevant.

Again, in my OP it was implicit that one should change (if possible/convenient) the way subs are actually called... it was meant to be a very generic cmt.
