Hm, interesting, so the structural relation between nodes in a graph is
provided by an iterator pointing to 0 or more of the neigbours in some
order. That could be applied to lists as well...
Still the reply is an iterator
pointing_to_this_neighbour, and then also
pointing_to_the_next_neighbour, and then also
..., and finally
???
O.K., I'll stop insiting and iterating.
