Hi,
I'm trying to bind boost::fusion::at_key, but i do not understand why the following piece of code do not compile :
struct tag
{
class a;
class b;
class c;
};
typedef boost::fusion::map<
bf::pair<tag::a, size_t>
, bf::pair<tag::b, size_t>
, bf::pair<tag::c, size_t> > TMyFusionMap;
TMyFusionMap aFusionMap(7,8,9);
std::cout << boost::fusion::at_key<tag::b>(aFusionMap) << std::endl; //work
std::cout << boost::bind(&boost::fusion::at_key<tag::b>, _1)(aFusionMap) << std::endl; //do not compile on msvc 8.0
std::cout << boost::bind<size_t &>(&boost::fusion::at_key<tag::b>, _1)(aFusionMap) << std::endl; //do not compile on msvc 8.0
any idear ?
