Research direction
Start by reviewing the existing stream-node APIs used in the zip_latest/filter/pluck example and compare how similar usage patterns are represented. Clarify whether the goal is a gate node, a super-node abstraction, or documentation before choosing an entry point. Done means one agreed approach with a defined implementation or documentation scope.

Description
It may be helpful to have a Gate node, or super node or at least some usage docs/pattern docs.
A gate node would filter one stream by another stream. This could be done by
s1 = Stream()
s2 = Stream()
l = s1.zip_latest(s2).filter(lambda x: bool(x[1])).pluck(0).sink_to_list()
We have some options in terms of implementation:
- Make a node to do this as syntactical sugar
- Create some sort of system for "super nodes" where there are underlying nodes but we can treat it as a single big node.
- Just document usage patterns like this one (and the average square and others)
I don't know which one is better.
