Ok well I guess waiting for the rest to be implemented isn't going to work
if y'all start implementing it on your own. :-)
Added to the spec, though without mentioning JSON, and with requirements
slightly different than JSON. Specifically:
- I used NOT_SUPPORTED_ERR instead of a generic Error in the case of
a cycle being detected.
- I allowed all Number values (including Infinity and NaN) to pass
- I didn't stringify host objects, I just converted them to null. This
avoids things like people putting DOMStorage objects in there and
seeing megabytes of data getting copied unintentionally.
- I made Array and Object cloning work basically the same, and made
them preserve order. In particular, [1,,2] survives intact (unlike
in either the JSON.stringify() spec or in implementations).
