Thanks for positing this. I worked on the raylib 4 bindings for Chicken 5. When chicken switched from version 4 to 5 many bindings needed a re-work. Anyways, raylib has tons and tons of bindings, and the once for Schemes are all somewhat incomplete(like Chicken and Gambit), some do not work at all(e.g. Chibi) and therfor need maintanance. As raylib is evolving so do the bindings and need constant enhancement and fine tuning. I hope projects like this will encourage more people to chime in and maybe help to improve things.
