This is what happens when a mediocre programmer reads too many Paul Graham essays, hacks his way through a couple of sections of SICP, and shamelessly rips off Peter Norvig's code in chapter 2 of PAIP.

Kids these days.... ;)

I only hope more mediocre programmers start doing the same.

You've got to give the guy credit for trying. His sources are sound - PAIP is difficult, and PG consistently rings true. I'd take him over a mainstream C# drone salivating over Biztalk.

I do like his update :

"A lisp hacker has rewritten my code to take advantage of more of the language's native featuresX eliminating a great deal of code in the process."
