Java's stream API needs more intermediate operations but instead of implementing some of them, Stream::gather, a new meta-operation, allows the JDK and us to implement all operations we need as Gatherers without overloading the `Stream` interface. Here's how to create Gatherers from an initializer, integrator, finisher, and combiner.
