Comment (by jeff@…):

 This is my adjusted function...


 {{{
 /**
  * Maps a function to all non-iterable elements of an array or an object.
  *
  * This is similar to `array_walk_recursive()` but acts upon objects too.
  *
  * @since 4.4.0
  *
  * @param mixed    $value    The array, object, or scalar.
  * @param callable $callback The function to map onto $value.
  * @return The value with the callback applied to all non-arrays and non-
 objects inside it.
  */
 function map_deep( $value, $callback ) {
         if ( is_array( $value ) || is_object( $value ) ) {
                 foreach ( $value as $index => $item ) {
                         $value[$index] = map_deep( $item, $callback );
                 }
                 return $value;
         } else {
                 return call_user_func( $callback, $value );
         }
 }
