Yes, but the final version of the C++17 standard was released as late as December 2017, so support may not be "production ready", neither in gcc nor in other compilers. You can the summary of the gcc c++ standard support here: https://gcc.gnu.org/projects/cxx-status.html#cxx17 https://gcc.gnu.org/projects/cxx-status.html#cxx17. Full support for all features in the c++17 standard, but the support is declared "experimental". Similarly here for clang: https://clang.llvm.org/cxx_status.html https://clang.llvm.org/cxx_status.html And Visual studio: https://blogs.msdn.microsoft.com/vcblog/2018/04/26/announcing-msvc-conforms-to-the-c-standard/ https://blogs.msdn.microsoft.com/vcblog/2018/04/26/announcin... (link to latest blog post, perhaps there is a status page that gets updated, but could not find it).
