 Some other stages which introduce concurrency include `.merge`, `.interleave`, `.groupedWithin` and [I/O](io.md) stages. The created channels serve as buffers between the pipeline stages, and their capacity is defined by the `BufferCapacity` in scope (a default instance is available, if not provided explicitly).
