> In my experience, recursion is the hard part ...
My limited experience has been different. I've been trying to make time to learn Scheme lately, and recursion seems simple enough. You can just practice it until it makes sense. What I find difficult is understanding what symbols are and what single-quoting actually means. No Scheme book I've seen yet just comes out and actually tells you in plain language what a symbol is.
Single quoting lets you pass a list without evaluating it.
(car (eval '(a b c))) vs. (car (a b c))
Do the same thing.
Have you read SICP? Somewhere in the 1st-3rd chapter there's an explanation of first-order evaluation that scheme uses. Once you know how scheme evals sexps, it makes sense that quote skips some of the steps of evaluation.
I strongly recommend the SICP/Little Schemer/Seasoned Schemer if you haven't heard of them.
Thanks for the explanation of the single quote. Can I convince you to add something about what a "symbol" is (and if it's connected in some way to the single-quote mechanism)?
Probably the first thing you want to do is put whatever is supposed to be on http://docs.racket-lang.org up because that's resulting in lots of broken links on the front page.
I think it would be appropriate to post again when the site is complete.
How is this change going to be implemented in Linux repositories?
I installed the old busted PLT/DrScheme via repo, will it get automatically updated to the new hotness Racket, or will I need to keep an eye out for a new package?
Since the documentation is'nt working, here's one question - is there anything similar to Leiningen for Clojure or , to a lesser extent, SBT for scala ?
I've often wondered if purpose-building a tool for visualizing recursive processes would help.
They could call it Ponzi.
