Description

I would expect these two traversals to be equivalent:

gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V(1).repeat(out().fold().unfold()).times(2)
gremlin> g.V(1).repeat(out()).times(2)
==>v[5]
==>v[3]

Also note something dkuppitz pointed out:

gremlin> g.V(1).repeat(out().fold()).times(1)
==>[]
gremlin> g.V(1).out().fold()
==>[v[3], v[2], v[4]]
