Review Comment:
Should we accept all of `UUID`, `GType.UUID`, `uuid`, and `GType.uuid` as
valid GTypes for consistency?
> Introduce Type Predicate
> ------------------------
>
> Key: TINKERPOP-2234
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2234
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.4.2
> Reporter: Stephen Mallette
> Priority: Major
>
> Provide for a {{typeOf()}} predicate that allows for testing the type of an
> object which would enable neat things like:
> {code}
> g.V().outE().has('weight',gt(0.1)).inV().path().unfold().is(typeOf(VERTEX))
> {code}
> See the linked DISCUSS thread for more information.
