zebra striping

Hi there,

First off, thanks to those who created/actively work on haml
- it's
just what the doctor ordered!

I had a question that I wasn't able to find an answer for
anywhere on
the web - that might be a bad sign.  I'm trying to zebra
stripe lists
using something like Ruby's cycle() view helper, but haml
doesn't seem
to like me even thinking about it.  Is there some easy, dead
simple
way that I'm just missing to zebra stripe lists with haml?

Thanks much in advance.

- Rob

Why have both 'odd' and 'even' when just one of them and an
empty one
is enough? Like cycle("","hi")

Excellent - yeah, it's a matter of style I guess.  I like
extracting
it out into a helper file that can take arguments (for
custom flip/
flop CSS classes).  Thanks for the tips!
