OK, from what I understand, it's similar to what we do as well, except Dispatch adds magic while we do it all manually. We have an event-based system: instead of await points, we fire events which are stored inside an AMQP broker. The broker has N consumers on different nodes which take new jobs as they arrive. Retries/circuit breakers etc. are added manually (via a Go library), and if a job/event handler fails, it's readded back to the AMQP queue (someone else will process it later). Inside event handlers/job processors we also enjoy Go's builtin local scheduler (so I/O calls do not block entire cores).

I can see the benefit that with Dispatch, logic is simpler to read/to write as just ordinary functions, while in our approach, we have to scatter it around various event handlers/job processors. However, I still like that in our approach, event handlers/job processors are entirely stateless (the only state is jobs/event payloads), I've found it to be good for scalability and reliability + easier to reason about, compared to passing around internal coroutine state.
