True enough :-)

FWIW, the itertools documentation style was intended more as a learning
device than as a specification.  I combined regular documentation,
approximately equivalent generator code, examples, and recipes.
Hopefully, reading the module docs creates an understanding of what the
tools do, how to use them, how to combine them, and how to roll your
own to extend the toolset.  Another goal was providing code fragments
to support scripts needing to run on Py2.2 (itertools were introduced
in Py2.3).
