Careful with that ||=, Eugene!
Did you really want to prohibit a cereal number of zero?

That's why I generally avoid using ||= to specify defaults.
Unless I'm very sure my incoming data won't ever be 0, "0", or "".

Besides, there are ways to tell if she is a witch:

$name = '' unless defined $name; $rank = '' unless defined $rank; $c_num = '' unless defined $c_num;
or:
foreach ($name, $rank, $c_num) { defined or $_ = '' }
or the strange-but-lovely:
$_ = '' for grep !defined => ($name, $rank, $c_num);
or the tried and true:
$name = '' if weight($name) == weight($duck); $rank = '' if weight($rank) == weight($duck); $c_num = '' if weight($c_num) == weight($duck);

Err...

Oh, yes, I should also mention that next week, when Apocalypse III and Exegesis III appear, you'll find that Perl 6 is going to have a much nicer way to solve this problem.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
