Can you talk about what the Scala-based traverser can express beyond Gremlin? I ask this cause Gremlin provides Turing completeness in function and path definitions. Thus it allows you to move through a graph in an arbitrary manner----explicit adjacency, probability distribution control, teleportations, path/function composition, etc.? --- though Gremlin lacks i/o manipulations of a traverser (e.g. data from a socket connection altering the traversal, file data, keyboard, etc).
