## Message

```
Sema: adjust coercion of undefined error union payload

To no longer set the error code to undefined. This fixes the problem
where an undefined single-item pointer coerced to an error union of a
slice set the whole thing to undefined even though the sub-coercion to
the slice would have produced a defined value.
