Async functions are a concept that only affects the internal structure of a function - to generate the state machine that allows yielding at `await` keywords and resuming after they resolve. Externally they are no different from "sync" Promise-returning functions. So they only thing that async functions do is enable yielding at the callsite, the `await` keyword is what actually yields at the callsite and you can await anything, not just async functions. Again: > I want to be able to designate a computationally-intense function call (just that call, leaving the other calls alone) as async so that control yields to the event loop. This is what `await` is - `await` yields. Non-await calls don't yield.
