Hi all,

I'm trying to use swindle. I hope it is not too off topic. I know clos
from programming some projects in CMUCL clos, based on "Object Oriented
Programming in Common Lisp" by Sonya Keene.
The first thing I tried was to run a simple clos file in swindle which
bummm, well... as you can imagine I had some problems.
I've seen the documentation (or better yet, the reference) of swindle
online, however didn't help much. Is there any tutorial, examples with
it, or something that can help me point out the differences and get

Another very important question, I have the possibility for college  to
implement a planner in CMUCL Clos, or in swindle. Is swindle stable
enough so that it doesn't bring me problems while developing the

Oh, if you wish to know, what I tried in swindle was:

(defclass fol-formula ()

(defclass fol-connective (fol-formula)
  ((arg1 :accessor connective-arg1 :initarg :arg1)
   (arg2 :accessor connective-arg2 :initarg :arg2)))

(defmethod print-object ((c fol-connective) stream)
  (format stream "#<Connective ~A ~A>"
          (connective-arg1 c)
          (connective-arg2 c)))

        -> God had a deadline...
                So, he wrote it all in Lisp!
