[Boost-users] [Fusion] Assignement from adapted struct to tuple

Hello all,
While I managed to assign an adapted structure to a fusion vector, I 
fail to assign the same structure to a legacy tuple. The doc doesn't 
mention the assignement operator between two sequences, but I though it 
would work. Am I missing something ?

#include <boost/fusion/include/vector.hpp>
#include <boost/fusion/include/adapt_struct.hpp>
#include <boost/fusion/include/boost_tuple.hpp>

struct my_struct {
     double a;
     int b;
     char c;
};

BOOST_FUSION_ADAPT_STRUCT(
     my_struct,
     (double, a)
     (int, b)
     (char, c));

my_struct src;
boost::fusion::vector<double, int, char> dest1 = src;	//OK
boost::tuple<double, int, char> dest2 = src;		//Fails
