(1) (concurrency TS)
future<void> make_ready_future();
(2) (concurrency TS)
1) If std::decay_t<T> is std::reference_wrapper<X> , then the type V is X&, otherwise, V is std::decay_t<T>
Creates a shared state of type V that is immediately ready, with the result constructed from std::forward <T> (value) , then returns a std::experimental::future
2) Creates a shared state of type void that is immediately ready, then returns a std::experimental::future

Return value

A std::experimental::future associated with the shared state that is created.
