A modern programming language that makes developers happier.

If I have:
```either {
   val id = ... // raises if not found

   // a bunch of operations that can raise
}```
And I need to record any failures in the other operations with the id in the first step, do I really need a nested either to do that?

You can use `withErrors` to map failures:

```either {
    val id = …

    withErrors({ it.withId(id) }) {
        // a bunch of operations that can raise
    }
}```


That's a really neat tricky with `withErrors` actually :heart_eyes:

Should we start a cookbook somewhere, would be great to have on the website if it contains "enough" recipes.
