YAML::XS from CPAN (http://search.cpan.org/dist/YAML-LibYAML/lib/YAML/XS.pm). For example: 

#!/usr/bin/perl -w
use strict;

package example;    # object definition

sub new {
    my $self = {};
    $self->{'data'} = pop;
    return bless($self);
}

sub getData {
    my $self = shift;
    return $self->{'data'}
}

package Main;

use YAML::XS;

my $eg = new example("Hello world!\n");
my $save = Dump $eg;    # object instance to yaml markup

# save yaml markup to file
open (EG, '>yaml.test') || die;
print EG $save;
close(EG);

$save = $eg = undef;    # clear variables

# now load yaml markup from file
open (EG, '<yaml.test') || die;
$save .= $_ while (<EG>);
close(EG);

# yaml markup back into object
$eg = Load $save;
print $eg->getData();   # proof!

Dump and Load are the YAML::XS commands.
