Comment (by johnbillion):

 Example use case of a multilingual plugin that wants to allow template
 files to be overridden on a per-locale basis:

 {{{
 $types = array(
         '404', 'archive', 'attachment', 'author', 'category', 'date',
 'front_page', 'home',
         'index', 'page', 'paged', 'search', 'single', 'singular', 'tag',
 'taxonomy',
 );

 foreach ( $types as $type ) {
         add_filter( "{$type}_template_hierarchy", function( array
 $templates ) {
                 $new = array();
                 foreach ( $templates as $template ) {
                         $new[] = get_locale() . '/' . $template;
                         $new[] = $template;
                 }
                 return $new;
         } );
 }
 }}}
