I have no particular "wants" in this area I was just trying to evaluate the two proposals. Thomas seems fine with your original proposal now. I thought you were suggesting above you should be using `fatal_error_in_progress()` instead, so I'm not sure if this is your final proposal. If it is then I'm fine with it. There's no perfect solution when it comes to error reporting.
Thanks.
