+==== Type Predicate
+
+The new `P.typeOf()` predicate allows filtering traversers based on their
runtime type. It accepts either a `GType`
+enum constant or a string representation of a simple class name. This
predicate is particularly useful for type-safe
+filtering in heterogeneous data scenarios.

Review Comment:
maybe the `Note on Types` section should have some user facing reference to
`GlobalTypeCache`? what about the provider docs for those trying to extend this
feature?

> 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.
