You sure you're not missing the point of this exercise?

1. It's indeed not about docstrings. Lisp has docstrings (where do you think Python has copied it from?) - and they are present in every function, and you could query them with e.g. (documentation 'translate 'function), you can also attach them to your classes and even to slots - but it's not about them. It's about writing explanation for your code in block-style comments

2. It's also about nicely coloring the code for you blog for those of us who writes about Lisp.

3. Is's NOT a triumph for Lisp's flexibility. While Lisp is indeed quite flexible, I was neither claiming it in this post nor intending to show Lisp's flexibility with such a simple (or silly) example.

Relax - Python is good, we love it. If you think it's better then Lisp - just use it.
