Great. But it seems this might take some time. While changes I proposed are quite simple requiring little work. As a proof of that I attach lexical_cast.hpp changed to cover what I proposed. I have added classic_lexical_cast which uses std::locale::classic() during the casting. Both version propagate std::locale object to be used. If traditional version is used a NULL pointer is propagated so nothing actually changes and overhead should be marginal. Adding a cat (or other function) which takes arbitrary object should be easy with this code however I have not done it since I don't need it. What do you think about those changes? Can they be included in Boost 1.40? Adam Badura
