That's a good question.

The education tooling is all optional (so their only impact is perceptual) DrRacket, teaching languages, and supporting libraries are all optional. (see Minimal Racket - just the compiler and package manager https://download.racket-lang.org/releases/9.0/#:~:text=SHA25... )

I'd like to know what tooling is missing from Racket that is available in major general purpose languages like C#, Java, or Common Lisp implementations?
