Description

My understanding is that the new ChildFailed signal will be generated when using watch. However, when using watchWith there is still no ability to discern between normal and abnormal child termination. Given,"The primary purpose of watchWith is to translate the termination signal into the message protocol of the watching actors (without using signals).", watchWith appears to be falling short on this goal.
