-------------------------------------------
Not printing anything is a little ambiguous no?

Does an empty set return null?
Maybe there needs to be a distinction between an empty result set and a null
result set. A successful execution should perhaps return an empty result set or
a bool? (thinking out loud)
> Make the "null" return in the gremlin console into something more
> understandable

> Issue Type: Improvement
> Components: console
> Affects Versions: 3.2.1
> Reporter: Jeremy Hanna
>
> A common question among new users is what is with the "null" return String in
> the console when there is a successful execution. An explanation is in the
> docs now (see note at bottom of
> http://tinkerpop.apache.org/docs/current/reference/#_mutating_the_graph
> section) but it would be nice to avoid it or make it more immediately
> understandable for new users.
> It's not a huge deal, but often comes up as a question from new users.
