When I started, my plan was to follow the course in Guile instead,
since the course is about the design method, and not the tools, but
I had to stop very early when I had to do some projects involving
graphics and animation.
Personally, I don't feel the need for something like DrRacket,
but it would have been nice to be able to find a Guile "canvas" or a
2D game library to play easily with basic graphics and animations.
