So I'm taking a class this semester that is a survery of various programming languages. Not really what I was expecting, as most of the stuff we are going over is old, outdated, and irrelevant; but there are a couple gems here and there. Our first project is all about Lisp. Specifically, Common Lisp. Right now I'm working on implementing Qucksort and Radix Sort in lisp, which hasn't exactly been easy for me. I find that thinking in Lisp terms is somewhat difficult, as it is such a massive paradigm shift from what I'm used to (C based languages). That being said, Lisp is wild, and it seems immensly powerful. Looking at some code on the net, the ability to do so much with so little code is intriguing to me. I recall someone on here studying some Lisp (Peyomp maybe?), and was wondering if any other have any experience with it. Thoughts, comments? Is/has anyone used this in a professional environment?
