Brian Mastenbrook and I each presented a paper at the 2005 International Lisp Conference, and we both thought it would be worthwhile to do a repeat performance for the Chicago LUG.
Brian's paper (with coauthors) is about Climacs, a syntax-aware editor writing in Common Lisp. It does controlled reparsing of text upon editing. He has nifty graphical demos.
My paper is on the ANSI Common Lisp conformance test suite that's distributed with GNU Common Lisp. It's had a large impact on many CL implementations, and I think the lessons learned in testing apply to other languages as well.
I'll let everyone know when we've scheduled these. Send suggestions for times/places to me or to this list.
