Here is the JSON parser I referred to in the previous post. It's not heavily documented because it's pretty close to a 1:1 translation of the specification.

There are some rough edges in this parser. The test suite includes the number 23456789012E666, which is out of range of IEEE doubles, and is read in as Infinity. While this value can be read in as something meaningful, it cannot be emitted, since there is no provision in JSON to express values like Infinity, -Infinity or NaN. The pretty-printer does not re-encode strings containing Unicode characters or escaped characters into a JSON-readable format. Finally, malformed inputs cause exceptions (error).
