The class template std::experimental::future extends std::future with the following operations:
- an unwrapping constructor from
future<future<T>>; - a member function
is_readyto query whether the associated shared state is ready; and - a member function
thento attach a continuation to the future.
However, there is no interoperation between std::experimental::future and std::future .
