It's interesting that you point this out because I've had debates with
people about the difference between:
if urlext in ['html', 'xml', 'php']:
and
if urlext in ('html', 'xml', 'php'):
I generally prefer the latter but I know folks who prefer the former.
What's interesting is that in both cases we're trying to ask if the
key is a member of a literal set, and to me, it makes no sense for
that literal to be mutable. So I also think Raymond's idea has merit.
