Yet another solution would be to use Class::Multimethods, and have
both constructors named
new:
package MyClass;
use Class::Multimethods;
multimethod new =>('$') => sub {
my ($class) = @_;
bless { name => '',
rank => '',
cereal_number => '',
}, $class;
}
multimethod new =>('$','$','$','$') => sub {
my ($class, $name, $rank, $c_num ) = @_;
bless { name => $name,
rank => $rank,
cereal_number => $cnum,
}, $class;
}
BTW, there'll be a new version of Class::Multimethods out in the next month or two that lets you define multimethods like they will (probably) be written in Perl 6:
package MyClass;
use Class::Multimethods::Attributes;
sub new :multi ($class) {
bless { name => '',
rank => '',
cereal_number => '',
}, $class;
}
sub new :multi ($class, $name, $rank, $c_num) {
bless { name => $name,
rank => $rank,
cereal_number => $cnum,
}, $class;
}

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).
