You have also misunderstood my concerns. I am not making any statement regarding the choice of target or object or source language (JS, JS, Roy). I am am objecting to the choice of metalanguage (JS). Haskell compiles to assembly but is not written in assembly! I am very serious. JavaScript is terrible for analysis and a huge waste on the server-side or mobile. Choosing JavaScript as the metalanguage for an implementation of an HM type system is strange. Why have an HM type system itself written in a type-unsafe way? Why artificially limit the analyzability of the language implementation which is pure and simply string(Roy) -> string(JS)? Roy looks like it has great potential and one of the reasons for that potential is its nascent type system. I want to take my pure Roy function library to ObjC, OCaml, C--, etc.
