  * Each object (this also means archetypes!) could have a few of these
  * "dangling" from it; this could also end up containing 'parse errors'.
  *
  * key and value are shared-strings.
  *
- * Please use get_ob_key_value(), set_ob_key_value() from object.c rather than
+ * Please use kv_get/kv_set/kv_del from object rather than
  * accessing the list directly.
  * Exception is if you want to walk this list for some reason.
