In my (abandoned) Racket book (which had a very specific positioning), I was going to introduce some of the non-Scheme iterators like `for/list` at the start, to help people do commercial work on the first day... and then later teach some more old-school Scheme-idiomatic ways to do things, with named-`let` and avoiding mutations to shoehorn. (Then, once people were comfortable with the less-familiar way, they could decide when to use which.) |
