Comment (by jaanos):

 Hi!

 > Are you looking for `Graph.neighbors` ?

 I had this, but changed to `edge_iterator` since `neighbors` does not list
 a vertex multiple times if there are multiple edges to it (so maybe this
 is something that should be changed?). Also, this covers digraphs without
 needing an additional `if`.
