If the goal is to parse JSON, i don't need to create JSON-specific source code
I'm sorry kid, the goal is as stated in >>260 to extend the parser. JSON is just an example, I picked it because I knew there was already an article that explained and implemented it, so I didn't have to do so, just for you.
Now, we're awaiting your "Yes, you're right /prog/, there are things that Lisp can do that C can't, due to it's set of strange limitations", thank you :^)
