What I meant was that If we choose to put this thing under
distance_all_pairs and add an argument returning the distance matrix, then
I would still like to have a method called distance_matrix() that would
call distance_all_pairs asking for the distance matrix. And I would want
to have that since I would like to have a method called distance_matrix()
as we do for the other mentioned matrices!
That being said I am now starting to doubt it is a good idea to mix this
distance matrix with the shortest path algorithm. Especially if we don't
have the indexed matrix thing and since (apperently) infinity is not
digested by matrices.
What do you think
