it would be nice if we had some consistency in the community around naming of these things. I think that
gremlin-php gremlin-scala gremlin-go gremlin-python gremlin-whatever should be the official Gremlin Language Variant naming patterns. That''s especially true if the other parallel thread to this has community consensus that these things should become TinkerPop maintained projects.
