         - encode did not catch all blessed objects, encoding their
           contents in most cases. This has been fixed by introducing
           the allow_blessed setting.
+        - assume that most object keys are simple ascii words and
+          optimise this case, penalising the general case. This can
+          speed up decoding by 30% in typical cases and gives

           in decode_json.
