[Boost-users] Why fusion::map<> types not the same?

Hi, Why 'type' is not same as 'expected' in the example below? using origin = boost::fusion::map< boost::fusion::pair

; using expected = boost::fusion::map< boost::fusion::pair ,boost::fusion::pair ;

using type = boost::fusion::result_of::push_back< origin ,boost::fusion::pair

::type;

static_assert(std::is_same::value, "error!"); The second question is, how can I get the same type as 'expected' when using 'result_of::push_back<>::type' ? -- Regards, niXman ___________________________________________________ Dual-target(32 & 64-bit) MinGW compilers for 32 and 64-bit Windows: http://sourceforge.net/projects/mingwbuilds/ ___________________________________________________ Another online IDE: http://liveworkspace.org/
