Comment (by Leinad):

 Yes that's correct. I think it's a c++11 feature, but we use this already
 in path.cpp:

  std::locale& path_locale()
   // std::locale("") construction, needed on non-Apple POSIX systems, can
   // (if environmental variables LC_MESSAGES or LANG are wrong, for
 example), so
   // path_locale() provides lazy initialization via a local static to
 ensure that any
   // exceptions occur after main() starts and so can be caught.
   // path_locale() is only called if path::codecvt() or path::imbue() are
   // actually called, ensuring that an exception will only be thrown if
   // is really needed.
     // [locale] paragraph 6: Once a facet reference is obtained from a
 locale object by
     // calling use_facet<>, that reference remains usable, and the results
 from member
     // functions of it may be cached and re-used, as long as some locale
 object refers
     // to that facet.
     static std::locale loc(default_locale());
     std::cout << "***** path_locale() called" << std::endl;
     return loc;
