I find it sad... that people like Erik Meijer, Mark Lentczer... (even Doug McIllroy recently demonstrated that there are 2⁹⁹ dialects of haskell!!) are not being heeded And this complaint could be greatly alleviated with one little leaf drawn from racket -- language-packs: teachpacks https://docs.racket-lang.org/drracket/extending-drracket.html Along with the single lightweight directive #lang https://docs.racket-lang.org/guide/Module_Syntax.html#%28part._hash-lang%29 It may naturally be asked how is #lang different from ghc's language "-X" options A teachpack would be a bunch of coherent -X options maybe along with a suitable prelude
