          When ``any_language=True`` is used, the function also looks
          into other languages to find a suitable value. This feature can be useful
          for "title" attributes for example, to make sure there is at least something being displayed.
          Also consider using ``field = TranslatedField(any_language=True)`` in the model itself,
          to make this behavior the default for the given field.
  
          .. versionchanged 1.5:: The *default* parameter may also be a callable.
