Can anyone suggest a more convenient solution to the problem I am trying to solve?
I was a little surprised that the function_input_iterator took its argument by reference -- it seems like such arguments are typically passed by value, allowing the client to use ref/cref. If you're able to use boost range, I think you can get a much more attractive syntax (example modified to work with g++ on windows). Using boost trunk: #include<cstdlib> #include<iostream> #include<iterator> #include<boost/bind.hpp> #include<boost/range/adaptor/transformed.hpp> #include<boost/range/algorithm/copy.hpp> #include<boost/range/irange.hpp> using boost::adaptors::transformed; class foo { public: typedef double result_type; result_type return_random() const { return std::rand() / (double)(RAND_MAX); } }; int main(int argc, char** argv) { foo bar; boost::copy( boost::irange(1,10) | transformed(boost::bind(&foo::return_random, bar)), std::ostream_iterator<double>(std::cout, "\n")); return 0; } HTH, Nate
