I've got code which transforms an incoming flow and invokes actions based on basically a state machine. Currently the code does a few weird things, so I need to refactor it to be more predictable. Is there a suspend fun Flow<R>.mapState(initial: T, fun: (T, R) -> (T, Flow<S>)): Flow<S> somewhere?

Can you give an example of how you would call it? There's fold and runningFold, but neither of them exactly matches the signature you wrote there.

Lemme take a look at them. I'm mostly looking to make the state transfer from one iteration to the next one very explicit

A suspend fun that returns a flow is generally smelly btw
