I understand your nervousness about extra arguments, but I've learned that they don't really matter in Perl. An analogy that comes to mind is filling a glass of water. If I hand you a cup and you pour a gallon of water into it, all I get back is a cup. I might make fun of you for being so sloppy, but who cares? After all, I have the cup of water that I wanted. Still, if it is important to you, you can enforce it with logic in your sub.
... but things like that risk making the code a little harder to read. In reply to Re^3: Format Style Opinions: my, ternary, subroutine
