Brad's example is incorrect, and is not in the FAQ.  Cliff's example
is the correct one, although I agree with him that it is not to be
recommended.

People ought to look at the FAQ when they talk about it.  They also
ought to look in it if they fear that their questions have already
been asked.  ;-)

The entry at
http://www.python.org/doc/FAQ.html#4.16
explains this quite well, and gives the correct expression.
