Hi, as you no doubt know Log::Any's approach is very minimalistic and I don't think you can really expect it to do anything other than send messages to the logger.

So I think your approach may be the best you can do on the producer side. But, do you really need to output with Carp functions if you are going to log the longmess at level critical? Couldn't you simply document that the log will contain the stacktrace and push responsibility onto the consumer to, well, consume it, and then just die tersely?

Hope this helps!
