in reply to Comparing undefined values

You mean something akin to the "identity equality" operators that I think Python, Ruby, and JavaScript have?
if ($x === $y) { ... } if ($a !== $b) { ... }
No, as far as I know, there's nothing for that right now, although Perl 6 probably has it.

    Yup, I think that would be it. Though right now I'd probably call it the "no, damn it, I really do mean equal" operator. Perhaps it would be uncommon enough that we wouldn't need to Huffman encode the name.
