It has been interesting to watch the Clojure community’s take on DSLs over time. Clojure is a Lisp, and Lisps are notorious for inventing DSLs, particularly after PG’s various papers promoted that as a superpower of sorts. Clojure has gone the other direction and, while it supports macros, it generally discourages their use unless you’ve tried everything else first. But it still encourages DSLs built from the native Clojure data structures. So, for instance Hiccup for HTML generation.
