Hmm... this almost works.  It does update multiple elements, but it's a bit
too simple to do what I need.  Here's kind of what I'm trying to do, syntax
just made up for second add...

html script: (html evaluator
    callback: [ :script |
        script add: (script element id: 'id1'; update: 'price here').
        script add: (script element id: 'id2'; 
            render: [:r | 
                self allPrices do:[:each | 
                    r text: each. 
                    r anchor callback:[self bookRate: each]; text: 'book
rate']])])

Ok, updating the first element, simple text content, works great, but
updating the second element, need to insert multiple child elements with
anchors and callbacks, need a rendering context, can't figure this one out.
Any ideas?
