They produce the actual tags, which are the basic objects resulting from the parsing stage. I don't think this can be easily replaced by Bison itself or Guile. Why is it hard to add these to Bison? It can handle embedded C code, so why not embedded Lisp code? It should be straightforward to make such changes.
