Gosh, https://gcc.gnu.org/projects/cxx0x.html and https://gcc.gnu.org/gcc-4.8/cxx0x_status.html seem to old and dated now. First, the standard before last has been published. Second, at some point, it can’t be experimental anymore. Would be nice if someone could update the content. The part about the concepts branch being dead is now wrong, it is alive again.
