In the Olden Days when I was writing FTX13, I used periodically to report on new versions of LISA, a production rule system for Common Lisp. As with so much of the other stuff that went into FTX13 I'd never actually downloaded it to try for myself, so these reports tended just to recycle whatever the project release notes said. The accrued boredom and low-level guilt from doing this over a six month period was one of the factors in giving up FTX13.
So, there's a new version of LISA out today (1.3), and I still haven't looked at it, and i still feel vaguely uneasy about this. Anyway, you can probably determine whether it's useful for you: see e.g. mab-clos.lisp
