[Boost-users] [Mpl, Fusion] using adapted struct with mpl algorithms

Hello Boost Users,

I've encountered a trouble using fusion adapted struct as mpl sequence:
when I call mpl::push_front with fusion::vector it works but if I try to
call it with
adapted struct, it fails. Do I miss something? Is there any concise solution
or
I have to convert it by hand?

   1. #include <string>
   2.
   3. #include <boost/fusion/adapted/struct/adapt_struct.hpp>
   4. #include <boost/fusion/mpl.hpp>
   5. #include <boost/fusion/container/vector.hpp>
   6. #include <boost/mpl/push_front.hpp>
   7.
   8. typedef boost::fusion::vector<std::string, int> employee_1;
   9.
   10. struct employee_2
   11. {
   12.   std::string name;
   13.   int age;
   14. };
   15.
   16. BOOST_FUSION_ADAPT_STRUCT(
   17.   employee_2,
   18.   (std::string, name)
   19.   (int, age))
   20.
   21. /* this line compiles just fine */
   22. typedef boost::mpl::push_front<employee_1, bool>::typebool_employee_1
   ;
   23.
   24. /* this fails */
   25. typedef boost::mpl::push_front<employee_2, bool>::typebool_employee_2
   ;
   26.
   27. int main() {
   28.   return 0;
   29. }

Thanks!
