Yes. If you print the list (1 2 3) it prints as a callable form, and then you have to get into reading, evaluation, etc. Aphyr's Clojure tutorial series went there. IIRC the second or third chapter was devoted to that. On the other hand, in the Racket curriculum, they define limited subsets of Scheme used as teaching languages; when the student first learns about lists, they construct them using cons and they print as cons forms, i.e. the (in-memory) list '(1 2) would print as (cons 1 (cons 2 (cons ()))) This is the kind of simplifications that are done in the teaching languages and that allow the course to avoid a number of advanced topics in the beginning. It avoids a lot of confusion at the cost of a small lie and an extra effort when you want to introduce macros and the "code is data" idea. (Which you usually don't want to do in an introductory course anyway.) For a short (and, I found, very enlightening) peek at the HTDP curriculum, you can skim through the Systematic Program Design course by Gregor Kiczales on edX: https://www.edx.org/xseries/how-code-systematic-program-design This is by a wide margin the best introductory programming course I have ever seen.
