I expect any language which needed this would need to define its own set of
values for each enumerated language-specific type.  We don't currently have
any attributes whose set of values is determined by the language.  So, this
would be a new precedent.  Perhaps it's better just to stick with a
C++-specific name and C++-specific values, and any other language would be
free to define its own similar attribute & values for each enumerated type.

I can't speak for Java or Fortran, but Ada wouldn't be able to use this
functionality.  Language-defined types and user-defined types really are on
equal footing with respect to overload resolution in Ada.  I wouldn't expect
that Fortran would either, but I haven't really kept up on newer versions of
Fortran.
