Given the heretical nature of the document, I wanted to keep the tutorial as anti-functional as I could. (Uh, just to make sure: that was a joke. In fact, I'd written a zipper tutorial for myself in https://hkn.eecs.berkeley.edu/~dyoo/plt/zippers.txt a few years ago.) I want to keep the number of concepts down as much as possible. There are two dangers I'm trying to avoid: 1. Losing velocity. The tutorial is meant to be read in one sitting. Anything that slows down the velocity of the reader means people's interest will drop. It's the reason why the PLaneT development-link section is so close to the front of the tutorial: that's basically the only time where velocity is just slowly starting up, and people will tolerate setting the link up then. 2. Narrowing the target audience down. I want to make it at least available to professional programmers with some familiarity (if not expertise) with a programming language like Scheme. Basically, I was trying to imagine someone like Randall Schwartz hovering over my shoulder as I was writing the tutorial. I hope I succeeded at that target audience in mind. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
