A co-worker loves Lisp and I've looked at a "quick-n-dirty" booklet - 
looks VERY VERY interesting. But, IMHO it's a waste of time to make one 
language look & act like another for it's own sake.

Can't overload operators in Javascript. IMHO eval functions would look 
funny and be clumsy with little benefit; again, just to make it "look" 
like LISP.

Javascript is "light weight" for a reason. Maybe you'll be better off with 
Java.

Hey, interesting questions. Some good academic experimental material here. 

Good Luck
