anchor.diff:  "iterating your traversal" is described further in link:http://tinkerpop.apache.org/docs/x.y.z/tutorials/the-gremlin-console/[The Gremlin Console Tutorial].
   
   In this first five minutes with Gremlin, you've gotten the Gremlin Console installed, instantiated a `Graph` and
  -`TraversalSource`, wrote some traversals and hopefully learned something about TinkerPop in general. You've only
  +`TraversalSource`, written some traversals and hopefully learned something about TinkerPop in general. You've only
   scratched the surface of what there is to know, but those accomplishments will help enable your understanding of the
   more detailed sections to come.
   
  
positive.code: ----
  
  <1> Get all the vertices in the `Graph`.
  <2> Get a vertex with the unique identifier of "1".
  <3> Get the value of the `name` property on vertex with the unique identifier of "1".
  <4> Get the edges with the label "knows" for the vertex with the unique identifier of "1".
  <5> Get the names of the people that the vertex with the unique identifier of "1" "knows".
  <6> Note that when one uses `outE().inV()` as shown in the previous command, this can be shortened to just `out()`
  (similar to `inE().outV()` and `in()` for incoming edges).
  <7> Get the names of the people vertex "1" knows who are over the age of 30.
  
negative.code: link:http://groups.google.com/group/gremlin-users[mailing list], a failing example put in the context of the toy graphs
  can usually get you a fast answer to your problem.
  
  TIP: When asking questions on the mailing list or StackOverflow about Gremlin, it's always helpful to
  link:https://stackoverflow.com/questions/51388315/gremlin-choose-one-item-at-random[include a sample graph] so that
  those attempting to answer your question understand exactly what kind of graph you have and can focus their energies
  on providing a good, tested answer rather than trying to build sample data themselves. The sample graph should just be a simple
  Gremlin script that can be copied and pasted into a Gremlin Console session.
  
  For your first graph, use the "Modern" graph, which looks like this:
