 Replying to [comment:61 ocean90]:
 > Something I missed to mention earlier: There is an issue with functions
 like `get_post_type_labels()`/`_get_custom_object_labels()`. Post type
 labels are initially registered via `register_post_type()` which means
 they don't change when calling `switch_to_locale()`. You can see that with
 [https://core.trac.wordpress.org/attachment/ticket/29783/user-language-
 admin-toolbar.php the example plugin] in the Add New menu for the Post and
 Page items.

 There are even more issues, for example, when you have a Custom Post Type
 or Custom Taxonomy registered by using a translated slug. When you switch
 to a different locale, the rewrite rules (and thus the generated
 permalinks) do '''not''' get adapted.

 The question is if coping with these things should be handled by the
 locale switcher, or not.
