Not sure why you went with Gerbil/Gambit - Gambit is usually marked as a hard-core Scheme, and you usually go with it if you need an excellent optimizing Scheme compiler without too much dance around it (it has a minimal interface). For Guile, you usually rely on OS package management to get modules or go with Guix. But if you want a "download, unpack it, run" Scheme, you go with Racket [1]. Tons of documentation, a good-enough JIT compiler, and usually everything works. You get an amazing IDE with it (DrRacket) with many advanced features yet to be found in modern IDEs for popular languages. > Oh and it uses square brackets for parameters Most modern Scheme implementations make square brackets and parenthesis equivalent. E.g. (let ((a 1) (b 2)) ...) ;; is the same as (let ([a 1] [b 2]) ...) [1] https://racket-lang.org/ https://racket-lang.org/
