> long story short: it's a mess to get a {{KStream<>[]}} out from {{KStream<>branch(Predicate<>...)}}.
It breaks the fluent API and it produces bad code which is not that good to maintain since
you have to know the right index for an unnamed branching stream.
> Quick idea, s.th. like {{void branch(final BranchDefinition<Predicate<>, Consumer<KStream<>>>...
branchPredicatesAndHandlers);}} where you can write branches/streams code nested where it
belongs to
