I believe this is similar to the 'class task' wrapper that Peter Dimov proposed in N2096 at http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2096.html I think easy to use wrappers are a vital part of implementing future. I'm not sure I see a great advantage to putting the wrapper functionality directly within the promise class constructor though.
