Read the last sentence in my message. Of course, if you're reading the
array in from a file or something it might make more sense to just set it
to the null string, "" so that when you loop over the array to use it your
check to see if the values are null is two-fold, it takes care of the case
where you removed the e-mail address and the case where there wasn't one
to begin with.
Like you said, we're not sure if Perl fixes the array when there's an
empty value or not.
