*** 13,18 ****
 With the advent of iterators and generators in Python 2.3, each of
 these tools can be expressed easily and succinctly in pure python.
! Rather duplicating what can already be done, this module takes the

 \subsection{Itertool functions \label{itertools-functions}}
 
+ The following module functions all construct and return iterators.
+ Some provide streams of infinite length, so they should only be accessed
+ by functions or loops that truncate the stream.
