At the Lisp50 event within OOPSLA in October, conversations between talks led to the question of what's next for Common Lisp. One candidate for extensions is Qi Lisp, which adds ML style of pattern matching while preserving access to all existing CL functionality and without being forced into a purely functional programming world. The second edition of the book is available which essentially freezes the language spec for the time-being. The print edition has been available for only a matter of days, so it doesn't get much newer than that! These are print-on-demand books, so for now, you must order directly from the publisher. Alternatively, you can read an HTML version on the web site. http://www.lambdassociates.org/ With that... Has anyone here experienced Qi yet? --either the current Qi II or the original from years ago? Thoughts? Opinions? I just received my copy of the book and previously went through the "Qi for Lisp programmers" tutorial on the web site. I'm intrigued and still learning the language. (In the mean time, however, ANSI CL is still my principal language.) Thanks, -Daniel -- first name at last name dot com (206) 250-9830
