  * Most of the time, you won't encounter two different static lists with similar contents used as element args,
  * meaning using static lists is accepted. However, should that happen, it's advised to replace the instances
- * with various string_x procs: lists, assoc_lists, assoc_nested_lists or numbers_list, depending on the type.
+ * with either string_list(), string_assoc_list(), string_assoc_nested_list() or string_numbers_list(), depending on the contents of the list.
  *
  * In the case of an element where the position of the contents of each datum list argument is important,
  * ELEMENT_DONT_SORT_LIST_ARGS should be added to its flags, to prevent such issues where the contents are similar
