Haskell has an option for it: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html#ghc-flag--XScopedTypeVariables OCaml has it built-in. I think SML has it built in too. It is fairly common in other words, and very useful. :-) -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
