There are (IMHO) two solutions:

1) Implement it ourselves, completely from scratch. This is generally
   possible, but anything more that straight R5RS (i.e. syntax-case)
   seems to hard. And we need something like this, since many core
   forms can not be implemented with syntax-rules

2) Port the freely available syntax-case package from Dybvig et al.
   to Chicken. This would have to be extended to allow embedding
   line-number information in syntax objects, though.
   AFAIK, SISC has taken this approach.
