Just for the completeness: there is a fourth option (injective vertices, non-injective edges): (a)-[e1]->(b), (a)-[e2]->(b). In this case, a and b have to be distinct, but e1 and e2 can match to the same edge.

Note that this CIP is in a heavy state of flux in order to allow for alignment with ongoing discussions.

Hello, are there any updates regarding this CIP? I am very interested in the proposed DIFFERENT operator functionality so I can use node isomorphism in contrast to the edge isomorphism.
