Lisping (written by the author of the article) purchaser here - a really interesting product.

Now, nit-picks with this article: mostly that Haskell and Scheme are not suitable for production.

I am fairly weak with Haskell. I have bought three books, read through parts of them, and played with a lot of little bits of code. My non-expert opinion based on reading people's and company's success stories with Haskell convinces me that either the language is fit for production or the people who use Haskell are great developers and can ship with anything. Probably both possibilities are true.

I do have a lot of experience with Scheme (I wrote a (not very good) Springer Verlag Scheme book in ancient times, once ported all of OPS5 from Common Lisp to Scheme in about 10 hours flat, and lots of projects...). I find Gambit Scheme great for writing small and efficient utility programs and the Racket system certainly has a lot of available libraires for getting stuff done.
