Maybe it could've occurred to you that I don't know Prolog yet, thus my post here. :P

How good is your Lisp?

LISA does forward chaining within CLOS, so you always have a real language on standby when you need one. JESS has Java.

Prolog: what a frustrating language to use in the Real World and what a delightful lab language.
