  implementation of the iterator protocol.
  
+ The intention of the protocol is that once an iterator's
+ \method{next()} method raises \exception{StopIteration}, it will
+ continue to do so on subsequent calls.  Implementations that
+ do not obey this property are deemed broken.  (This constraint
+ was added in Python 2.3; in Python 2.2, various iterators are
+ broken according to this rule.)
