docs: Returns an iterator over the raw registration arguments of each option in this parser.
  
      Each yielded item is an (args, kwargs) pair, exactly as passed to register(), except for
      substituting list and dict types with list_option/dict_option.
  
      Note that recursive options we inherit from a parent will also be yielded here.
