// fusion::vector::at_impl requires specialization of mpl::int_
// (and doesn't work with other Integral Constants).

#include <iostream>
#include <boost/mpl/integral_c.hpp>
#include <boost/mpl/int.hpp>
#include <boost/fusion/sequence/container/vector.hpp>
#include <boost/fusion/sequence/generation/make_vector.hpp>
#include <boost/fusion/sequence/intrinsic/at.hpp>

int main()
{ 
  using namespace boost::fusion;
  namespace mpl = boost::mpl;
  
  std::cout << at< mpl::int_<0> >( make_vector("hello","bug")) << std::endl; // OK
  std::cout << at< mpl::integral_c<int,0> >( make_vector("hello","bug")) << std::endl; // ERROR
  
  return 0;
}
