For parser errors and division by zero errors (and friends), I want to flag a more serious error-level than for "expected" errors.

I think you are on a hiding to nothing trying to interpret the meaning of exceptions from unknown code.

For example: What if the code already traps a division by zero error, but then re-throws it (via die) but with some other text that makes sense in the context of that particular module? (Say: "Average calculation failed: zero datapoints supplied." or similar.)

How are you going to classify that? Is it one of your "more serious" errors or an "expected" error?

I really don't think there is any sensible way for a generic logging module to categorise the seriousness of exceptions thrown by unknown code.

And even if there was, I'd suggest that it shouldn't anyway. A logging module should log; not interpret.

(Probably not what you want to hear, but its just an opinion. Then again, I reject the whole Test::* suit of modules primarily because they mess with my output; and thus get between me and my quickest route to solving bugs; all in the name of producing pretty printed garbage statistics.)
