>> 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.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.

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.	[reply] [d/l]
