Unfortunately, the first example I tried to create (which was very basic) broke in IE. I see things like commas after the last item in an array in their generated code, which will break. Works in Chrome and Firefox though. So they've got some work to do. I would expect slightly better in a preview version, though. I don't expect production quality, but I also don't expect it to generate code that will quite obviously be broken in the most popular browser.
