And this is only the pipeline scanner defines the syntax like that. The syntactical check to verify that unused streams do not get connected prevents a lot damage from typing mistakes. Other means to construct a pipeline can make stages where only one of the pair of streams is defined. But then you're on your own building the topology. -Rob
