+1. This would be a big help for developers, if only in that it will tell
us what exceptions we ought to do this with.
IMO, this is probably important enough to make it a builtin; maybe call it
CriticalExceptions or some such.
Also, maybe in 2.5 we could begin warning about bare excepts that aren't
preceded by non-bare exceptions.
