+==== 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?
