Uhm....as usual @havvg 's right about this method. Anyway, imho it could be useful for our users to return data failures in different formats. What do you think about extending `ConstraintViolationList` to expose some methods like `toArray`, `toJson` etc.?

```php
class PropelConstraintViolationList extends Symfony\Component\Validator\ConstrainViolationList
{
    public function toArray()
    {
        // Return array
    }
}


// In our controllers
$failures = $model->getValidationFailures()->toArray();
```
