    Create the Subscriber or VirtualPublisher that consumes the incoming stream, plus the materialized value. Since Subscriber and VirtualPublisher do not share a common supertype apart from AnyRef this is what the type union devolves into; unfortunately we do not have union types at our disposal at this point.
