Does this include libc++ (compiled shared library of the STL complete with headers and debug symbols?) Although I hate most parts of the STL I still find myself using some parts of it (std::vector, std::string, <algorithm>, <type_traits>, etc.). Maybe I can link libc++ as an external library but then that's too much busywork needed for Zig to be a complete C++ dev environment out-of-the-box.
