    +==== Changed infix behavior
    +
    +The infix notation of `and()` and `or()` now supports an arbitrary number of traversals
and `ConnectiveStrategy` produces a traversal with the correct AND and OR semantics. Furthermore,
    +previous versions failed to apply 3 or more `and()` steps in an infix notation, this
is now fixed.

    +[source,groovy]
    +----
    +gremlin> g.V().has("name","marko").and().has("age", lt(30)).or().has("name","josh").and().has("age",
gt(30)).and().out("created")
    +==>v[1]
    +==>v[4]
    +----
    +
    +In previous versions the above traversal 
    +[source,groovy]
