I have question about the plan to migrate code base from C++03 to C++20 for iostreams library
I think iostreams library have very more clean if using modern C++ features, such as Concept
Did you have any plan about that?
thanks
Lots of people use boost because they cannot use C++20 or even C++17. For those users, boost provides C++11 or C++14 portable equivalent of new std libs (boost::optional, boost::variant, boost::filesystem, etc.) If boost required C++20, many users would not be able to use boost anymore. Boost should be not require such a recent C++ standard. C++11 or C++14 are probably the best minimal standard for Boost IMO at the moment. Furthermore, looking at https://en.cppreference.com/w/cpp/20 (core language + STL), recent versions of gcc or msvc are in good shape with C++20 but clang is less complete. Dominique
