I like how the disclaimer went humble bragging about the range of usage.

>"Please don't assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and Ecommerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list."

He left out Guessing Animals!

>While in high school, he saw output from one of the guess the animal pseudo-artificial intelligence (AI) games then popular. He considered implementing a version of the program in BASIC, but once at the Massachusetts Institute of Technology (MIT), instead he implemented it in several dialects of Lisp, including Maclisp.

The core route optimization algorithm of Routific is also written in Common Lisp :)

That's awesome, thank you. How do you know it, is there a reference on the net somewhere?

I wrote it :) there’s also an open source version here: https://github.com/mck-/Open-VRP
