I used std::task::Poll as Progress (is not as confusing and I liked it more than Option).

Unfortunately, this didn't fix the fail. I'll investigate it tomorrow.

Let's add a custom enum for this

enum PendingBinding {
    Pending,
    Ready(Option<NameBinding>)
}

, and add a helper method fn binding(&self) -> Option<NameBinding>, it will be more convenient.
