in thread undef==defined sometimes?

I think I 'resent' the syntax that @a=1, is an assignment to $a[0]...

Why would you resent that and not resent that @a = (1, 2, 3) is an assignment to $a[0], $a[1], and $a[2], respectively? (Don't make the mistake that the parentheses have anything to do with list creation; they only exist for grouping, as the precedence of the assignment operator is higher than that of the comma operator.)

    chromatic, please tell merlyn to incorporate this post into the next Learning Perl ed. (where he says to do @empty = () instead of @not_empty = undef as it would have clarified this concept much sooner for me as well. The info is there but not specifically for this point.
