Comment (by jeff@…):

 This replacement function seems much better ...

 {{{#!php

 function map_deep( &$value, $callback ) {
         if ( is_array( $value ) || is_object( $value ) ) {
                 foreach ( $value as $index => $item ) {
                         if ( is_object( $value ) ) {
                                 $value->$index = map_deep( $item,
 $callback );
                         } else {
                                 $value[$index] = map_deep( $item,
 $callback );
                         }
                 }
                 return $value;
         } else {
                 return call_user_func( $callback, $value );
         }
 }
 }}}
