Dear all,
so, is there any interest in making a CDR BoF at ECLM or ELS? I have a few ideas about a (short) list of topics for discussion.
I am curious about how many CDRs have been implemented in how many lisps over the last seven years. This information may not be easily available, but anything that anyone knows will be interesting.
There's no CDR about it, but there's an informal convention that when a CDR is implemented, a keyword :CDRn is pushed onto *features*. We should probably write a CDR about it. If we rely on it, then only one CDR is implemented on only one implementation. clall -r '(list (lisp-implementation-type) (find-if (lambda (x) (string= "CDR" x :end2 (min 3 (length (string x))))) *features*))' Armed Bear Common Lisp --> ("Armed Bear Common Lisp" :CDR6) Clozure Common Lisp --> ("Clozure Common Lisp" NIL) CLISP --> ("CLISP" NIL) CMU Common Lisp --> ("CMU Common Lisp" NIL) ECL --> ("ECL" NIL) SBCL --> ("SBCL" NIL) But actually, AFAIK, all the CDR defined so far can be implemented as libraries. -- __Pascal Bourguignon__ http://www.informatimago.com/ A bad day in () is better than a good day in {}. You can take the lisper out of the lisp job, but you can't take the lisp out of the lisper (; -- antifuchs
