Have I ever been serious? … ah, yea, but people already have their own variants with those names, like, for example, Gremlin-Scala! :D And I don't think (or maybe I'm wrong) that we want to take in, for example, Gremlin-Scala into TinkerPop? -- and all the others? ………. gets back to the TinkerPop2 days when MongoGraph was in our repo.
