Hi, Boost.Typeof seems to implement native typeof by using compiler bug or extension. Can decltype(reference sensitive) be implemented by using compiler bug or extension? Regards, -- Shunsuke Sogame

Boost.Foreach already implements compile time rvalue detection for some compilers: #if BOOST_WORKAROUND(BOOST_MSVC, >= 1310) && !defined(_PREFAST_) \ || (BOOST_WORKAROUND(__GNUC__, >= 4) && !defined(BOOST_INTEL)) \ || (BOOST_WORKAROUND(__GNUC__, == 3) && (__GNUC_MINOR__ >= 4) && !defined(BOOST_INTEL)) # define BOOST_FOREACH_COMPILE_TIME_CONST_RVALUE_DETECTION For these compilers, it is possible to implement decltype. I am not sure whether this should be part of Boost.Typeof, since we cannot implement this feature on the remaining compilers. Regards, Peder Regards,

I wanted to use decltype in order to make boost::result_of compilation faster. (So that, the portability could be kept anyway.) I probably give up, after all. I've applied Boost.Typeof when expression type is known rvalue. Unfortunately, the compilation time becomes slower :-) Regards, -- Shunsuke Sogame
