+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.
