But running that script just does nothing but gleefully print a
newline.
mhh? It won't print a newline, it even won't print anything.
b/c @ar is empty, for(...) doesn't go into it, 'print' won't be happened.
Yeah your right... (what was I thinking...) but my point was that it
seems perl should say something about this. It seams at least as
significant as trying to use an undeclared var.
I would say it was more like
$total = $total + $value;
when $value was zero. Would you expect a warning then?
