 The lack of an `async()` call makes futures awfully cumbersome to use.  I
 hacked up this nullary prototype for C++03.  It's better than nothing!

 {{{
 #!cpp
 #include <boost/thread.hpp>
 #include <boost/utility/result_of.hpp>

 template <class F>
 boost::detail::thread_move_t<boost::unique_future<typename
 boost::result_of<F()>::type> >
 async(F f)
 {
     typedef typename boost::result_of<F()>::type R;
     boost::packaged_task<R> pt( f );

     typedef boost::unique_future<R> future;
     future ret = pt.get_future();
     boost::thread( boost::move(pt) ).detach();
     return boost::move(ret);
 }
 }}}
