What happened
A tutorial introducing Racket, tracing Lisp's lineage from McCarthy's 1958 original through Scheme (1975) and PLT Scheme (1995, renamed Racket in 2010). It highlights Lisp-originated concepts now ubiquitous in modern languages—garbage collection, first-class functions, REPLs, expression-valued conditionals, and homoiconicity—and positions Racket as a 'language-oriented programming' tool for building custom DSLs quickly.
Why it matters
Most working builders won't switch to Racket, but the article is a useful on-ramp if you want to understand homoiconicity and macros deeply—concepts that increasingly surface in AI prompt engineering and code-generation tooling where treating code as data matters. If you're evaluating DSL design for internal tooling or agent workflows, Racket's 'build a language in an afternoon' pitch is worth a weekend experiment, not a production bet.
Discussion angle
Whether language-oriented programming and homoiconicity ideas from Lisp are relevant again in the age of LLM-generated code and agent tool-use, or whether they remain academic curiosities for most builders.
