trait Futures {

    fn poll(&mut self, wake: fn()) -> Poll<Self::Output>;
}

impl<T> Poll<T> {
    pub fn map<U, F>(self, f: F) -> Poll<U>

            Poll::Pending => Poll::Pending,
        }

}

enum Poll<T> {
    Ready(T),
    Pending,
}

fn my_function() /* -> impl Futures<Output = ()>*/
{
    println!("I'm an async function!");
}
