Right, if you want to enumerate the fieldnames of a JSON object, then
you'd probably have to use the JSON parser.
You could probably use a JSNI method in an overlay type to return an
array of field names, then have another JSNI method in the object that
would return the field, the problem becomes handling field types. you
return a JavascriptObject, but that object is opaque, you don't really
have any way to determine its actual type, so you would have been
better off just parsing in the first place.
