async fn bar(input: u32) -> i32 {

> If only we were allowed to execute the code up to the first await point, then we could get rid of the Unresumed state. But "futures don't do anything unless polled" is guaranteed, so we can't change that.

Is that actually valid reasoning? If we know that foo(blah) doesn’t do “anything” until polled, then why can’t bar call foo without polling it before foo itself is polled? After all, there’s no “anything” that will happen.
