I think that I could change

sub set_power {
    my $self=shift;
    my $power=shift;
    push @{$self->{POWERS}}, $power;
}
sub get_powers {
    my $self=shift;
    my $num=1;
    foreach my $power ( @{$self->{POWERS}} ) {
    print "$num => $power\n";
    $num++;
    }
    print "\n";
}

into something like:

sub power {
    my $self=shift;
    if ($_[0]) {  
        my $power=shift;
        push @{$self->{POWERS}}, $power;
    } else {
        my $self=shift;
        my $num=1;
        foreach my $power ( @{$self->{POWERS}} ) {
        print "$num => $power\n";
        $num++;
        }
        print "\n";
    }
}

It would be called as $obj->power("Power name") to set, and $obj->power() to view.
