in reply to Re^3: scanning hash
in thread scanning hash

need to change that slightly so it will return true if all the keys are undef:

return 0 unless defined $_ ? $_ eq $value : defined $value ? 0 : 1

    No, I don't.

    $ perl -le'print undef eq undef' 1

    Update: oh, I see what made you think that. I had to NOT my XOR condition. I forgot that XOR produces false rather than true if both operands are equal.
