No, I'm not looking for examples in Elm necessarily, I'm looking for realistic problems that are solved in a simple way with observables so that we can figure out how to solve them in Elm and if we need some additional language constructs or libraries to be able to solve them. There may very well be a case for some kind of asynchronous stream construct, but it's not at all obvious that we should use the same construct as for instance RxJS.
Like the double click or swipe example, but with a more complicated state. The state for double click and swipe is pretty simple to model in Elm, it's just a matter of saving the time of click and the number of clicks. Even if Elm would have kept it's signals, they were not the kind of observables you have in RxJS. For asynchronous messages you have to use Commands/Tasks anyway.
