A stream can depend on any number of streams and it's guaranteed to update atomically. For example, if a stream A has two dependent streams B and C, and a fourth stream D is dependent on both B and C, the stream D will only update once if the value of A changes. This guarantees that the callback for stream D is never called with unstable values such as when B has a new value but C has the old value. Atomicity also bring the performance benefits of not recomputing downstreams unnecessarily.

You can prevent dependent streams from being updated by returning the special value `stream.HALT`
