[Reviews] Futures - packaged_task and shared_future
Hi, can you consider the ability of a shared_packaged_task to return a shared_future? This is a temporary use case until we have implementation of containers allowing movable_only object. unique_future<T> is movable_only and can not be stored on current containers as for example fusion::tuple.

You can move a unique_future<T> into a shared_future<T>, which can then be stored in a container. boost::packaged_task<int> pt(some_func); boost::shared_future<int> f=pt.get_future(); // move-assign Anthony -- Anthony Williams Author of C++ Concurrency in Action | http://www.manning.com/williams Custom Software Development | http://www.justsoftwaresolutions.co.uk Just Software Solutions Ltd, Registered in England, Company Number 5478976.

Excelent. I like this integration. Vicente
