      Problem with std::swap and <tuple>. A cutdown test case is:

      #include <tuple>
      struct S00{
      S00() = default;
      S00(const S00&) noexcept {}
      S00(const S00&&) noexcept {}
      S00& operator=(const S00&&) noexcept

      { return *this; }

      } s00;

      typedef std::tuple<S00> T00;
      T00 t100(s00), t200(s00);
      const bool b00 = noexcept(t100.swap(t200));

      template void std::swap<S00>(T00&, T00&) noexcept(noexcept(t100.swap(t200)));

      This seems to be a parser bug.
