@dandrabik IMHO, the `safe_to_replay` method *is* configuration, so it's ok to recreate it in config. NBD either way.


So just to make sure I understand this YAML format, to skip replays for all errors of a particular class, you put an empty string as the message value:

```
TimeoutError:
  - ''
```

And since we're using `class.to_s`, we can't use an ancestor class/module. Could be a gotcha down the road.
