> I don't think we have a tool for this currently. However, I'm not sure that right and left are relevant terms for this case. Also: what do you do in the case when three lines meet at a node. What would be the 'next_left_edge line' ?

right, these terms comes from TopoGeo model based described in ISO 13249-3:2006.

See eg.
