For all you new guys, you should really start using the Canvas API right
off the bat, it's much easier to use and much more consistent than the
old HtmlRendering API.

The above would be something like...

 renderContentOn: html
 	html text: 'foo = ', (foo asString); break.
 	(html anchor) 
          callback: [self setfoo];
          text: 'set foo'.
	html break.
