JSON.pairs() method is available.
Since JSON.entrySet() returns the REAL entry set of JSON, which means the values may be the JSON.Quotation objects (if some quotation is made), so the entrySet() method is not suitable for getting the key-value pairs. Now, JSON.pairs() can do this, it would get the FINAL object (if quoted) in the entry set.
Also, a bug is fixed in JSON quote feature.
