If anyone wants to try the flavour of Scheme used in the book, install Racket and use:
#lang simply-schemeback

Note that it doesn't get installed by default. You must download the package https://pkgs.racket-lang.org/package/simply-scheme
The easiest way is to go to inside DrRacket and open the menu File > Package Manager and add "simply-scheme".
Or if you prefer the command line, something like
raco pkg install simply-shemeCool, I just started using Racket this week, for prototyping an S-expression based DSL.
