The ToString formatter should invoke s.toString() which is either Object.toString() or whatever is overridden. Since javascript does not do this automatically like java does whenever converting an object to a string it would make sense to do this, otherwise ToString is really a noop.

Yes, good point. The 'str' formatter is defined as "an implementation-specific string representation for the JSON node".

I added you as a member to the project. Can you provide a patch for review? See here:

Thanks. This also points to the need for JavaScript-specific tests...

There are a few other issues I really want to tackle before I just go on to patch up the little problem in the JS impl (and more might become visible as I really go through all of it).

However this is a trivial fix :) Sure why not.

In javascript the standard is the .toString method, though Java casts all objects using the .toString method when converting them to a string, javascript does not do this automatically. But the Object object has it.

Fixed in r194.
