> I haven't looked at {{ExpandableIterator}} in over a year. Its one of the
> most fundamental structures of a Gremlin traversal. I just realized it can
> take an entire {{TraverserSet}}. As such, if the previous step is a
> {{Barrier}}, don't iterate the barrier out, simply "dump it" into the current
> steps {{ExpandableIterator}}. That should speed up things significantly --
> though there are not that many barrier steps... but still.
