in thread Clearing Array Values

$#array=() is equivilent to $#array=0 (since () is a zero-element list)

If you mean that () returns 0 in scalar context because the parentheses are empty you're way off. In the expression $#array = () there is no list. The parentheses are used for precedence only! There's no such thing as a list is scalar context -- or at least not that I know of. Since there's nothing inside the parentheses the undefined value will be returned.
