For example, a SignalProducer could have multiple observers that are set up to receive events sent on the signal, but the signal won’t become active and the observers won’t see any events until it is started by something. A signal is started by calling start() on it.

• The other new type is Signal. A Signal is like a firehose. You hook it up to a source, and events travel through it. There is no starting of a Signal, so you can’t use it to kick off work in the same way a SignalProducer can. Signals also can’t maintain any history. When something begins observing a Signal’s events, it w
