I'm not sure I like this polymorhic method-naming stuff that'll be happening in the background. Perl is weakly-typed, so why do a work-around that strongly-typed languages have to do? Instead, why not do the following?
sub new {
my ($class, $name, $rank, $c_num) = @_;
$name ||= '';
$rank ||= '';
$c_num ||= '';
bless { name => '',
rank => '',
cereal_number => '',
}, $class;
}
That, to me, just feels cleaner and is more maintainable. If you make a change in
new(), you only have to change it in one place. Especially if it's in a base class. If it's in a base class and you only change one, you suddenly have weird behavior in the grandchild classes and debugging it would take an age-and-a-half. *shudders*

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).
