 ==== Loop Section
 
-The loop section makes it possible to iterate over an instance of `Iterable`, `Iterator`, array, `Map` (element is a `Map.Entry`), `Stream`, `Integer` and `int` (primitive value).
+The loop section makes it possible to iterate over an instance of `Iterable`, `Iterator`, array, `Map` (element is a `Map.Entry`), `Stream`, `Integer`, `Long`, `int` and `long` (primitive value).
 A `null` parameter value results in a no-op.
 
 This section has two flavors.
