Hi, I have a question on StateFlow: is it possible to fold a flow into a stateflow? I.e. is there a function like
```fun &lt;T, R&gt; Flow&lt;T&gt;.foldToStateFlow(initial: R, op: (acc: R, next: T) -&gt; R): StateFlow&lt;R&gt;```

Doing the fold and turning it into a state flow are really two different things. The type of fold you're looking for is called `runningFold` (alias `scan`), but it returns an ordinary flow, not a state flow. To get a state flow, you would still need to provide a coroutine scope and use an operator like `stateIn` to actually collect the upstream values. It's kind of a pain that `runningFold` and `stateIn` both want the `initial` value, though... I'm not sure what's the cleanest solution to that little conundrum.

Great, `runningFold` was the missing link. That works for me! Thnx!
