Then we end up with a flow of flows (`Flow<Flow<String>>`) that needs to be _flattened_ into a single flow for
further processing. Collections and sequences have [flatten][Sequence.flatten] and [flatMap][Sequence.flatMap]
-operators for this. However, due the asynchronous nature of flows they call for different _modes_ of flattening,
