> Allow the grammar to support parameters similar to how the groovy engine does
> like, {{g.inject(x,y,z)}}. Doing this will make it easier for a transition
> away from the groovy engine as a lot of Gremlin in the world today uses
> parameters. The grammar may have to come with some limitations though as
> groovy is wide open in terms of what can be treated as a variable. Probably
> going to keep parameters tied to primitives, collections and tokens/enums
> like {{Order}} and {{Scope}}. Collections themselves will not contain
> parameters and things like a {{Traversal}} or {{P}} cannot be treated as one.
