lack of SFINAE is a real showstopper for me. I want to write functions like

template <typename T> typename result_of::type operator-(T const& x) { return negate()(x); }

but the lack of SFINAE here makes boost::result_of essentially useless for this. But I imagine it won't be difficult to make a new version based on boost that would work.

FWIW: template<class T> T make(); template <class T> BOOST_TYPEOF_TPL(make()(T())) operator-(T const& x) { return std::negate<T>()(x); } Regards, Arkadiy
