> On TINKERPOP-2621 we allowed the grammer to properly process empty {{P.within/out()}}. From there a next step would be to optimize those a bit:
> * {{has(key, within(''))}} is always false in which case we can replace within('') with false.
> * {{has(hey, without(''))}} is always true in which case this step/HasContainer can be removed from the traversal as a filter.
