I _knew_ there had to be a way to avoid it, and it was frustrating me 
that I didn't see it. Good job finding it. And it's so simple..... But 
not obvious without doing the detailed trace that you did.

btw,
change

   my $limit = index $item, ')';

to

   my $limit = index $item, ')';
   $limit = 0 if $limit < 0;

and the seed from '()' to '', and you should be able to handle n=0.
Oh, it looks like you have to move the print test to the start of the while loop.
