my $bottom_node = Getopt::LL::DLList::Node->new('bottom');
$head_node->set_next( $middle_node );
$middle_node->set_prev( $head_node );
$middle_node->set_next( $bottom_node );
$bottom_node->set_prev( $middle_node );
my $current_node = $head_node;
while ($current_node) {
print $current_node->data, q{, };
$current_node = $current_node->next;
}
# prints: top, middle, bottom
