I don't understand the part about go, does that mean go doesn't require async but gives you the functionality of async? (I never tried go)
The problem with async is that we can separate when to start a task and when to ask for its result. The compiler can just add await everywhere an async function is called, it is trivial, but you don't get the flexibility of async. If everything is treated as async, you will need to await everything (perhaps some syntactic sugar to allow for immediate await)
