Re: [Boost-users] [function] generalization of std::plus and std::multiplies with more than one argument type

but I need this generalization of multiplies as one of the default parameter of a template, how would you pass a lambda expression as template parameter?

As a part of my workj on Boost.SIMD, i have a generlized fucntor with result_of protocol support and tag-dispatching. Basically : functor<plus>()(x,y) return the sum of x and y for the correct semantic of + for the type of x and y. result_of::type returns it result type. Is that smthg like that you need ?
