 An iterator is an object representing a stream of data; this object returns the
 data one element at a time.  A Python iterator must support a method called
-``next()`` that takes no arguments and always returns the next element of the
-stream.  If there are no more elements in the stream, ``next()`` must raise the
-``StopIteration`` exception.  Iterators don't have to be finite, though; it's
