So, I guess you don't know why OP specifically asked about Racket: https://www.cs.utah.edu/plt/dagstuhl19/ https://beautifulracket.com/stacker/why-make-languages.html

Nah, I know about Racket's DSL support and touting itself as friengly to language writing, but it's still not the same as a dedicated parsing toolkit, the same way I wouldn't consider a Lisp with reader macros equivalent either...
