Hi, Here is the get_list method in Data::Container package: 
sub get_list {
    my ($self, @capwords) = @_;
    my $items = $self->{items};
    my @list = ();
    return @list unless $items;
    foreach my $item (@{$items}) {
    push @list, $item if ($item->is(@capwords));
    }
    return @list;
}

The get_list does return an array.
Thanks for the hint you provided. I understand it now better.
One final question though. In the package Library, I have the following:
sub get_list {
    my ($self, @keywords) = @_;
    return $self->{lib}->get_list(@keywords);
}

The method Library::get_list will actually return the result of Data::Container::getlist. Is my understanding correct?
