You should write more ;-)
I also posted your "Adding Reflection to C" at https://news.ycombinator.com/item?id=49964525 and hope HN picks up on it and has a decent discussion.
You definitely should add a detailed post on your "DrC" compiler/interpreter; usecase, scope, techniques used etc. Since this is looking forward to C2y/C29 with some more extensions, i think people will enjoy playing with it in the REPL format.
