Yes, see e.g. Params::Validate
update
An example:
#!/usr/bin/perl
use strict;
use warnings;
use v5.10;
package Player;
use Params::Validate qw(:all);
sub new {
my $class = shift;
my %attr = validate(@_, {name => 1, race => 1});
return bless \%attr => $class;
}
package main;
my $player = Player->new(race => 'Elf', name => 'Legolas');
# dies: missing attribute
my $player2 = Player->new(race => 'Dwarf');
# dies: unknown attribute
my $player3 = Player->new(race => 'Hobbit', name => 'Bilbo Baggins', s
+ize => 'small');
say 'done';

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 How to display code and escape characters
are good places to start.
