Looks cool!

I pulled from your branch and stumbled upon commit
7d1c45d38e34659c1ec3b76ba4c985901123bf61 entitled "fix macro compilation
via hooking into eval-case", which will probably lead to discussions.
;-)

I wanted to try a few things to refresh my memory on that topic, but it
appears that `pprint-glil' is currently broken:

  guile> (use-modules (system il compile) (language scheme translate))
  guile> (define hi (translate '(use-modules (srfi srfi-9)) (make-module)))
  guile> (define lo (compile hi (make-module)))
  guile> (use-modules (system il glil))
  guile> (pprint-glil lo)

  Backtrace:

Any idea?

Surely you can achieve similar results more quickly using the REPL?

Thanks,
