Obviously. The whole point of this proposal is that awaiting async functions is automatically _implied_ inside an `autoasync` function, unless an async function is called with a `background` qualifier (which thereby makes it return its promise instead). The OP is right: this is a far less bug prone way to do async programming than `async` `await`, while offering all its functionality, with the added bonus of transparently allowing sync functions to be converted to async functions without fundamentally affecting consumer calling code.
For those who want to be able to do extensive async programming, having this in the language, and using it instead of `await` `async` throughout, is a no-brainer. Of course, I am qualifying that it must be new keywords, not `await` `async` juggled like in the original post, but that wasn't the thrust of the proposal anyway.
