Description

We should allow mid-traversal V() and E(). It shouldn't be a technical problem, since we always know the traversal source, thus it's just a simple flatMap. Vendors could then implement mid-traversal global index lookups.

Example:

g.V().hasLabel("company").has("name", "DataStax").in("worksFor").as("dse").
  V().hasLabel("company").has("name", "Aurelius").in("worksFor").as("ae").
      addOutE("dse", "knows", "ae", "since", "02/2015")
