Missing Flow operators

See original GitHub issue

ReceiveChannel is missing some very useful extension functions

.combineLatest() .distinctUntilChanged() .switchMap() .merge() .scan() .filterIsInstance()

Would it be possible to add these?

Hopefully, channel will implement the same interface as cold stream and we will implement operators once and for all

I’d love to see more overloads for the combineLatest operator, or at least one combineLatest operator that takes a List<Flow<*>> so I can create my T1…Tx combineLatest functions myself.

In RxJava I really often use the pattern of combining the latest emissions of an observable into a view state:

Observable.combineLatest(userStream, recipeForId(id), foodFavoritesStream, userSettingsStream, ::buildViewState)
