I just gave two reasons:
- Concurrency / interactivity. The main thread shouldn't wait for all
one million items to be produced to get to see even one of them.
- Limiting resources. Just like iterating over the lines of a file is
more memory efficient than reading the whole file in memory, getting
each consumed item as it becomes available is more memory efficient
than waiting for all of them to finish.
