Treatment for gnus-article-wash-html?

[pete-temp-12-29-2002@kazmier.com]

Is there any reason why there isn't a treatment variable for
gnus-article-wash-html?  I'd like to be able to force some of my
nnrss:groups to invoke gnus-article-wash-html automatically.  I
basically want to do something like this in my .gnus:

(setq gnus-treat-wash-html     '("^nnrss:Lamba"))

In this case, my Lamba the Ultimate RSS feed sends HTML that would
automatically be washed.  Right now, I have to always type 'W h' which
is a bit tedious.  

I'm a Gnus/Emacs/Elisp newbie (1 week), but I did take a peek in
gnus-art.el to see if I could get it to work, unfortunately, I had no
success.  I tried to do something like this:

Any help or pointers would be appreciated.  Perhaps I'm not even going
about this the right way.

Thanks!
