`Either` is not an Elm type (as of v0.19)

I got an error while using Either in Haskell

```elm
type alias Player =
{ name: String
, rating: (Either String (Int, String))
, delta: String
, positionChange: String
, country: String
}
```

It tried to use exactly the same type and even use the `jsonDecEither` helper, but this types are not valid in Elm anymore, I guess the recommended way should be to output `Result` instead? 🤔
