Racket has a much more advanced macro system than scheme's traditional syntax-case.

Yes, it certainly has, but I think it's still based on that traditional syntax-case stuff. So in theory other Schemes could perhaps copy it, if anyone can get all the macrology behind it. Also in theory it should be possible to express all the advanced Racket stuff in syntax-case.

Do you think it is not possible to express these things in syntax-case? And if so, why?
