Sounds like we’re agreeing - nobody _wants_ to write async code cos it’s terrible. You didn’t quite perfect the syntax above but I’m not denying it’s possible - Clojure treats async as a library, not a fundamental language feature, for example. And now with Loom the implementation is even simpler. People want to write synchronous code that can run in parallel without having to do something weird. History will hopefully prove that this is best solved as an implementation detail, not as part of a language’s semantics.
