EDIT - please ignore - the question resolved around a simple typo. I need a break.
How do I access a reference to an element of a boost fusion vector?
Unlike boost.tuples's tuples::get<i>(variable) (returns a reference), the fusion::at_c<i>(variable) returns a constant and this causing me difficulties.
The following illustrates my problem
#include <iostream>
#include <boost/tuple/tuple.hpp>
#include <boost/fusion/include/vector.hpp>
#include <boost/fusion/include/at.hpp>
using namespace boost;
int
main (int ac, char **av)
{
fusion::vector<int, char, std::string> vec(1, 'x', "howdy");
tuples::tuple <int, char, std::string> tup(1, 'x', "howdy");
std::cout<< fusion::at_c<0>(vec)<<std::endl; //outputs 1
std::cout<< tuples::get<0> (tup) <<std::endl; //outputs 1
//fusion::at<0>(vec) = 2; //doesn't compile
tuples::get<0>(tup) = 2; //works fine
std::cout<< fusion::at_c<0>(vec) <<std::endl; //can't make this output 2.
std::cout<< tuples::get<0> (tup) <<std::endl; //outputs 2
}
