 WordPress fails silently when wp_embed_register_handler() has a non-public
 callback

 If you have a class like this:

 {{{
 class Stuff {
    public static function hooks() {
      wp_embed_register_handler( 'foobar', $regex, array( __CLASS__,
 'embed_handler' ) );
    }

   private static function embed_handler( $matches, $attr, $url, $rawattr )
 {
     //.... do stuff
   }
 }
 }}}

 And you run
 {{{
 Stuff::hooks();
 }}}

 Your handler is never registered and no error is shown or logged.

 By contrast, `add_action()` checks for this condition and logs an error:

 {{{
 PHP Warning:  call_user_func_array() expects parameter 1 to be a valid
 callback, cannot access private method Stuff::enqueue_scripts() in
 /srv/www/wp/wp-includes/plugin.php on line 505
 }}}
