It seems quite plausible to decide to log an exception and then get another trivial exception raised and caught on the way to the logger. You would still want to log the original exception, so passing it explicitly is helpful sometimes.

[Trent]

Yes, I suppose so.

I'd like to call YAGNI on this. Also on the idea of being able to pass an exception to all logging levels. Also on the idea of passing the exc_info in rather than having the logger call sys.exc_info().

Instead, the logger should be subclassable or extensible so that Jeremy can implement this functionality if he really wants it.

What's the point here? I've presented use cases, and I maintain a large body of ZODB/ZEO code that already uses these features. So it simply doesn't make sense to say "You Ain't Gonna Need It" because I already need it and zLOG already has it.

The feature is simple to explain and implement, and seems to have low implementation cost. So I certainly think it meets the simplest thing that could possibly work criteria.
