    Description

      with 6.5.3, i'm getting this error, while with 6.5.2 the code works fine.

      Applications/Xcode13.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/concept:318:1: error: Parse error at "::"

      this somehow smells like being related to QTBUG-83160 and https://gitlab.kitware.com/cmake/cmake/-/issues/25117

      the stl code in question is:

      namespace ranges::inline __cpo {
  inline constexpr auto swap = __swap::__fn{};
} // namespace ranges::__cpo

      maybe the compiler defines `inline`, which causes moc to choke?

      xcode 14 and 15 don't suffer from this issue, nevertheless i wonder if there's a way around it
