The code that I need to “duplicate” is indeed a pain in the ass, since are both 2k files from Css and CssJs definitions: styled-ppx/packages/css/js/Css_Js_Core.ml at main · davesnx/styled-ppx · GitHub styled-ppx/packages/css/js/Css_Legacy_Core.ml at main · davesnx/styled-ppx · GitHub
I could eventually write them in ReScript and transform it to OCaml, but its painful.
