------- Comment #9 from paolo dot carlini at oracle dot com 2010-01-21 15:48 ------- Jack, I would ask you to have a bit of patience, because this code is in flux. Just a few days. In the meantime, if you want to experiment, I would suggest two things: 1- Always use up to date sources, r156097 is already old; 2- Remember to update *all* the occurrences of that _Fn::result_type, also inside the body of async(launch, _Fn&&, _Args&&...) for example; 3- Before spending too much time in the interaction between lambdas and <future>, double check lambdas per se, because we have some outstanding issues, in particular for lambdas with no captures as function pointers.
