A goroutine-and-channel implementation may not work as well for the "durable" goal, while this implementation is focused on being able to perfectly serialize the state of the Coroutines in order to resume them elsewhere (durable).

Honest question, why not use another technology to store the state between the two? Like a DB or queuing mechanism.

I guess the internal state of the coroutine won't be automatically preserved. Say you're emitting numbers from an rng. Theoretically with this you could restart the program while keeping the internal rng state so a restart would continue emitting new values from the same sequence; with channels you could preserve the emitted values, but you couldn't automatically save and restore the rng state so the values would diverge from a continuous run at some point.

The library provides a way to serialize coroutine state, and to later deserialize that state and resume a coroutine from its last yield point. Where you store this state (in a DB, in a queue, etc) is up to you!
