Just saw a video on why this is by Douglass Crockford....
Technically, you can use unquoted labels ala {var1:"value1"}, but
JavaScript will have errors when you try to use reserved words like
"for" and "switch".
Rather than write the JSON standard for labels using:
Attribute names can be unquoted as long as they are not these words:
for, which, ...
Crockford decided to just require that labels in object literals must
always be quoted.

json_encode should also produce valid JSON, which this isn't:

That is a valid JavaScript object literal, so it will work in most cases
when the "JSON" code is being loaded by JavaScript, but if you ever need to
feed JSON into a strict JSON parser it won't work.
Valid JSON for this would be:
{"ok":true,"state":"OUT-DECOMMISSIONED"}
IOW, all labels must be quoted, and all quotes are double quotes, not single
quotes. See http://json.org/ for the full syntax.

Jake,
json_encode is very cool, and it looks like it would take care of
everyone's problems...
THANKS!
