Review Comment:
Actually yes, that makes sense. I'll make the change.
> Maybe we call the enum InstanceOf rather than Type- that's pretty normal
and understood?
I agree. I was a bit unsure of the name as well but couldn't think of a
better one. `InstanceOf` sounds like a good alternative. Or `ClassOf`? `IsA`?
> 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.
