> shows how powerful Racket can be for building programming languages!

Building languages was always one of selling points racket tried to push; the "Language-Oriented Programming Language" slogan and all.

And it's true, and one of the reasons that Racket (and other beefy Schemes) is easily tied for my favorite language.

But I have to use other languages, like Python, JavaScript, and Swift, for employability and (sometimes) ecosystem/integration reasons.
