Although I guessed correctly here, a better answer for the archive is:
Perl doesn't have NULL strings, so you can't test for them. Perl
has undef values, empty strings, strings that have only newline,
strings with only white space, strings that are false, and those
are all testable with various predicates. But none of those are a
one-to-one match with "NULL". So the question is unanswerable as
stated.
Yes, I just made this up. :)
