Hi Lincoln,

I'm a total novice with the PERL debugger, but I took Ewan's suggestion
to play with it, and I seem to have gotten it to pass all
tests.  

The only change I made was:

if (defined $result) {
to
if ($result) {

To be honest I'm not sure why it works, and perhaps I've broken something
else in there?  It just seemed reasonable to me that since you had already
done a
my $result
then
if (defined $result)
would always be true and enter the loop.

Does this help at all?
Paul
