Yeah, I think that is much less error-prone. The `consumeError` method has a 
relevent comment:

```
/// Uses of this method are potentially indicative of problems: perhaps the
/// error should be propagated further, or the error-producer should just
/// return an Optional in the first place.
```

In this case it was just problematic to instantiate an `Error` right at the 
start, instead of when an actual error condition occurred.

So I agree that your proposed approach is better. There is still one 
`consumeError()` in there, though?
