Racket and Rhombus are nice for writing embedded DSLs, yeah. More generally, they're nice for writing macros. Scheme in general is nice for writing macros with its `syntax-case` and first-class notions of syntax objects, but Racket is /really/ nice with its `syntax-parse` and explicit notions of phase levels... If you are interested in learning, Greg Hendershott's "Fear of Macros" is often recommended as a good introduction. https://www.greghendershott.com/fear-of-macros/
