I want to be able to bind an > empty object as well. I'm not sure I understand the request. (json-parse-string "{\"a\":null, \"b\":{}}" :object-type 'plist) => (:a :null :b nil) (json-parse-string "{\"a\":null, \"b\":{}}" :object-type 'plist :null-object :null-object) => (:a :null-object :b nil) By binding :null-object, you can distinguish these objects already, so :empty-object would just be the opposite? And you can do that in post-filtering if you want something like that. But I've added Philipp to the CCs; perhaps he has a comment here. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
