Hello, could the futures library add support for following construct: ft::simple_future< int > f1 = boost::bind( fac, 4); ft::simple_future< int > f2 = boost::bind( fac, 8); ft::simple_future< int > f3 = boost::bind( fac, 10); ft::future< int > f_or = f1 || f2; ft::future< fu::tuple< int, int > > f_and = f_or && f2; // doesn't compile because no match for 'operator&&' in 'f_or && f2' thx, Oliver
