              << fs::path("/foo/.bar").filename() << '\n'
              << fs::path("/foo/bar/").filename() << '\n'
              << fs::path("/foo/.").filename() << '\n'
              << fs::path("/foo/..").filename() << '\n'
              << fs::path(".").filename() << '\n'
              << fs::path("..").filename() << '\n'
