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.
