I've been thinking about this some more, and the requirement that the caller be able to tell apart the NSResolver returning a String and some other object that has a toString() method is actually a bit of a pain. For example, in Gecko a C++ caller into this API would just get back a string object (basically the result of |returnValue + ""| or so). Telling where this string came from would actually be pretty difficult in this case.

Things get even worse if you allow non-JS implementations of NSResolver, because at that point the requirement doesn't even make sense.

Is there a strong reason not to just stringify whatever the NSResolver returns?

The current editor's draft already requires any object returned to be converted to a string, with the only special requirement being that null and undefined are converted to, or at least treated as empty strings.
