> Tuple0 is not cleanly integrated:
>   - missing serialization/deserialization support in runtime
>  - Tuple.getTupleClass(int arity) cannot handle arity zero, ie, cannot create an instance of Tuple0
> Tuple0 is currently only used in Python API, but will be integrated into Storm compatibility, too.
