[Boost-users] Re: Re: Re: Re: Re: result_of tutorial

Thanks Peter, I think I understand how it works now. Unfortunately, the 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. Cheers, Ian
