std::experimental::shared_future

Defined in header <experimental/shared_future>
template< class T > class shared_future;	(1)	(concurrency TS)
template< class T > class shared_future<T&>;	(2)	(concurrency TS)
template<> class shared_future<void>;	(3)	(concurrency TS)

The class template std::experimental::shared_future extends std::shared_future with the following operations:

an unwrapping constructor from future<shared_future<T>>;
a member function is_ready to query whether the associated shared state is ready; and
a member function then to attach a continuation to the future.

There is no interoperation between std::experimental::shared_future and std::shared_future.
