Small idea: Since Arc does major surgery on traditional Lisp syntax quirks, I think it should reclaim < and > as parenthesis, rather than symbol characters. Instead of (< n 0) you'd write (lt n 0), and use < for something else.
Not really, the Arc Challenge specifically discounts code for setting up libraries. All the script is doing is setting up libraries and loading your code.
You're both wrong, there are plenty of people working on CL and Scheme, and to every experienced Lisper I've spoken to, newLISP is a gigantic disappointment.
Since we're now all throwing out unsubstantiated claims, I would like to add the following ad hominem attack: You're both ugly too.
