I have tried it out in elm-lang.org/try, which suggests that it is asynchronous, in a simple setup - button that sends a DoStuff message - in update, the DoStuff branch outputs DoMore - update also logs all messages - the setup also contains a basic subscription to Time, with a Tick every 10ms The log then shows that between the DoStuff message and the DoMore message, a Tick message comes in. This is an extreme example, I admit, but with subscriptions to server messages, mouseovers etc, there is no telling when messages come in. So my takeaway was: if you want something done synchronously, handle it inside a single update cycle. If the community agrees that using Cmd Msg as you suggest is a valid pattern with valid use cases, then the (simple) helper would be a useful addition to a Task (or Platform? or Platform.cmd) package. The fact that we do not agree on this, makes it an interesting discussion here.
