[Pharo-users] Serializing to/from Json

Hi, I'm hoping to use CouchDB for storage on a seaside application. It would be lovely if I didn't have to serialize/de-serialize by hand to json for all my persistent objects, and could use instead something like a smalltalk version of Google's Gson library. Is there anything like that? I've tried the JSON library bundled with SCouchDB and it seems to automatically handle simple objects (eg, where the inst vars reference Strings or Numbers), but not handle more complex objects. Also, I haven't seen anything that de-serializes from json. Thanks much! Larry
