I copied the prelude that DrRacket adds when I save a beginning-student-language file with it and ran it with racket. I get %racket beginner.rkt cond: all question results were false context...: /home/dbastos/public_html/rkt/beginner.rkt: [running body] % (Very nice.) But I'm unable to run the prelude inside the REPL. That'd be this passage below. #reader(lib "htdp-beginner-reader.ss" "lang")((modname bst) (read-case-sensitive #t) (teachpacks ()) (htdp-settings #(#t constructor repeating-decimal #f #t none #f ()))) After #reader, it seems to always expect more and more input. So my strategy didn't work for the REPL.
