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.

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).
