Coroutine builder `coroutineScope {}` will return when the provided suspend block and child coroutines end.
Instead, is there anything that returns immediately when the block returns, cancelling child coroutines? I thought there would be prebuilt builder.
This would be extremely useful on situations like:
```coroutineScope { // this suspends until someFlow is finished; needs alternative one
  val collected = someFlow.shareIn(this, ...)
  work(collected)
}```

Ideal one to me:
```(some cool name)Scope { // someFlow.shareIn is cancelled after work is finished and block returns
  val collected = someFlow.shareIn(this, ...)
  work(collected)
}```

I think you can just call `coroutineContext.cancelChildren` when done.
I’ve never needed such a function. Generally using `WhileSubscribed()` is enough to avoid forever running shared flows.
