Does the Java API have a composition operator for SerializableFunction? It seems like these two compositions in particular might tend to pop up from time to time:
myFunction(KV::getValue(x)) myFunction(KV::getKey(x)) If there isn't already one, would there be interest in a contribution of one, or is it too trivial? https://github.com/wtanaka/streaming/pull/86/files --- Wesley Tanaka https://wtanaka.com/
