Thanks! Right, so the successful version was the one written in Lisp. Okay, that's actually understandable. At that time, managed languages were not widely used

Thanks! Right, so the successful version was the one written in Lisp. Okay, that's actually understandable. At that time, managed languages were not widely used, and C is really not a good choice for that kind of project. If those are the two options, I can certainly see how Lisp would do better.
