I’m getting the following build error:
```
Error:Kotlin: [Internal Error] java.lang.IllegalStateException: Backend Internal error: Exception during code generation
Cause: Back-end (JVM) Internal error: Error type encountered: [ERROR : For SuccessOrFailure] (ErrorType).
Cause: Error type encountered: [ERROR : For SuccessOrFailure] (ErrorType).
```

Full error here: <https://gist.github.com/sanity/e596fc3b5ff6b3f02f415fd9dc2e00d3>

I’m using the latest 1.3 RC (this happens both with builds 57 and 80).  Any ideas?

Why do you use old builds instead of 146?
