Hi! I would like to use the boost::zip_iterator with std::pair. Unfortunately this does not work out of the box, but there exists a namespace boost::detail::tuple_impl_specific, which apparently needs to be specialised for each tuple type. I managed to re-implement tuple_meta_transform and tuple_meta_accumulate for std::tuple, which seems to be straightforward. However, there are functions of the form template<typename Tuple, typename Fun> complex_result_type tuple_transform(const Tuple&, Fun) which have to be overloaded as well, if I am not mistaken. However, overloading this with something like template<typename... Args, typename Fun> complex_result_type tuple_transform(const std::tuple<Args...>&, Fun) is probably not going to work, since this would be a partial template specialisation of a function. What is the recommended way of proceeding here? Or am I making things to complicated and there exists a simpler solution to using the zip iterator with std::pair / std::tuple. Any support would be appreciated. Regards Claas P.S: I am using boost 1.50 with gcc-4.6 and the C++11 standard.
