  +IMPORTANT: image:groovy-logo.png[width=175,float=left] Gremlin-Groovy leverages the link:http://groovy.codehaus.org/[Groovy 2.x language] to express Gremlin traversals. One of the major benefits of Groovy is the inclusion of a runtime console that makes it easy for developers to practice with the Gremlin language and for production users to connect to their graph and execute traversals in an interactive manner. Moreover, Gremlin-Groovy provides various syntax simplifications.
  +
  +TIP: image:gremlin-sugar.png[width=100,float=left] For those wishing to use the Gremlin2 syntax, please see <<sugar-plugin,SugarPlugin>>. This plugin provides syntactic sugar at, typically, a runtime cost. It can be loaded programmaticaly via `SugarLoader.load()`. Once loaded, it is possible to do `g.V.out.name` instead of `g.V().out().values('name')` as well as a host of other conveniences.

   Here is the same code, but using Gremlin-Groovy in the <<gremlin-console,Gremlin Console>>.

  Or, if the vertex marko is already realized with a direct reference pointer, then the traversal can be spawned off that vertex. This illustrates that vertex (as well as edge) also have `GraphTraversal`-return methods and an exploration of their respective JavaDocs will demonstrate what is available.
  
  [source,groovy]
  gremlin> marko = g.V(1).next()
  ==>v[1]
  gremlin> marko.out('knows') <1>
  ==>v[2]
  
negative.code: ==>ripple
  ==>lop
  
  NOTE: In TinkerPop2, the `repeat()`-step was called `loop()`. Repeat has been generalized to support both do-while and while-do semantics which is explained in <<repeat-step,Repeat Step>>.
  
  CAUTION: A Traversal's result are never ordered unless explicitly by means of <<order-step,`order()`>>. Thus, never rely on the iteration order between TinkerPop3 releases and even within a release (as compiler optimizations may alter the flow).
