| 4 | | - Is it necessary that all the arcs in a path are directed in the same direction? Or we could store oppositely directed arc in a path as well? How should we define the source/target? Would the source node be equal to `gr.source(path.front())` and the target to `gr.target(path.back())`? |
| 5 | | - Should paths store source and target nodes explicitly? It would make it possible to handle paths of zero length (with a specified starting node). |
