Thanks to all for the feedback. I think I've seen slightly more votes
for enumerate than for itemize, and after some thought I think the
LaTeX example (where enumerate creates numbered items) *does* help --
even if few Python users know LaTeX, I trust the linguistic
sensibilities of LaTeX' author.
So enumerate() it is. (Specifically not enum() because of the C/C++
meaning of that word.)
