In this package, it wont get any values but stats_change... 
    package item;
    use strict;

    sub new {
        my $proto = shift;
        my $class = ref($proto) || $proto;
        my $self  = {};
        $self->{FILLABLE}    = undef;
        $self->{NAME}   = undef;
        $self->{VAL}    = undef;
        $self->{ATYPE}  = undef;
    $self->{VOL}    = undef;
    $self->{MASS}    = undef;
    $self->{DESC}    = undef;
    $self->{RACE}    = undef;
    $self->{stats_change}  = [];
        bless($self);
        return $self;
    }
           sub name {
        my $self = shift;
        if (@_) { $self->{NAME} = shift }
        return $self->{NAME};

        if (@_) { $self->{VAL} = shift }
        return $self->{VAL};
    }
           sub atype {
        my $self = shift;
        if (@_) { $self->{ATYPE} = shift }
        return $self->{ATYPE};

When i dump the values of an example of this, i get... 
 $VAR1 = bless( {
                 'DESC' => undef,
                 'stats_change' => [
                                     19,
                                     3
                                   ],
                 'ATYPE' => undef,
                 'VOL' => undef,
                 'NAME' => undef,
                 'VAL' => undef,
                 'MASS' => undef,
                 'FILLABLE' => undef,
                 'RACE' => undef
               }, 'item' );
