I'm not sure what point you are trying to make anymore.

Of course you cannot distinguish between unrecoverable and recoverable panics, because by definition an unrecoverable panic is not recoverable. There is no caller to distinguish between it - it is killed.

Oh. You're using the word panic to describe a superset of actual panics and other even more serious errors. Those things you call unrecoverable panics are not actually panics.

The point I'm trying to make is that panics are not errors by another name, and they are not safe to recover from in general.
