+==== 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:
> This predicate is particularly useful for type-safe filtering in
heterogeneous data scenarios.
the examples should demonstrate that better since this is deemed
"particularly useful". how about:
```
g.V().values("age","name").is(P.typeOf("Integer"))
```
to drive this section.

> Priority: Major

> Provide for a {{typeOf()}} predicate that allows for testing the type of an
> object which would enable neat things like:

> g.V().outE().has('weight',gt(0.1)).inV().path().unfold().is(typeOf(VERTEX))
