I think we are getting the cart way before the horse. I'd like to see at 
least the outline of an API before we go any further. JSON is, shall we 
say, lightly specified, and doesn't appear to have any equivalent to 
XPath and friends, for example. How will we extract values from a JSON 
object? How will we be able to set values inside them? In ECMAScript 
it's not a problem, because the objects returned are just like any other 
objects, but that's not the case here. These are the sorts of questions 
we need to answer before we look at any implementation details, I think.
