I really hope Colin finishes this as I've always thought Lisp would be a better beginner language if there was a book like mine for it. You've either got "The Little Schemer" series, which is annoyingly written for little kids but close to the style, or you have giant academic tomes that only hard core geeks would bother reading. A "trainer" book like mine would definitely solve this gap.

The intro is a little bit copied but it's fine since he is keeping to the idea and the "rules" I have, but could be nicer if it was in his own voice more. Who knows, maybe he does write like me a lot or he's just ultra inspired.

The big reason I say people should use their own words, apart from copyright, is that if you're writing one of these books for a programming language you love then your words will express that better. You'll say things that come from your community and culture, and you'll give away a sense of what you like about that language. When people copy what I say the prose comes out obviously not by them and not for that language.

Anyway, this is pretty cool and I hope he works on it some more.
