------------------------------+----------------------
 Add this behavior to future/shared_future::then()

 - In case of implicit unwrapping, the validity of the `future` returned
 from `then` cannot be established until after the completion of the
 functor passed into `then`. In such case, the resulting `future` becomes
 ready with an exception of type `future_error`, with an error code of
 `future_errc::broken_promise`.
