Would be awesome if we could figure out a way to do that.
The compiler is reflected into Arc so if all you need to do is make compiler changes you can do that by modifying "ac" or the functions it calls such as "ac-call". If the feature also needs to make runtime changes then we might need to add some hooks to the runtime to enable that.
