Sure! But it's really the educational material of How to Design Programs (HtDP) [1] that comes with DrRacket that makes the experience of learning the "right" patterns an easier experience than it might otherwise be. Also, this list is one of the friendliest lists you'll find anywhere, with people of all experience levels getting along well, where questions no matter how simple or complicated are almost always answered by people who will point you in the right direction. As for what language is best, though I like Racket a lot, the principles of HtDP can be applied to many languages. When it comes to recursion, the first thing to learn is when a recursion should stop. Then you learn that a recursive call is a natural and succinct way to compartmentalize computation to the thing you are looking at right now, combined with the result of similar computations that are aggregated elegantly through recursion. Later you learn how to make recursive calls efficient. -- Geoffrey S.
