Another one for the file of "Crazy shit Andrei says" ;)

>From experience, I (and clearly many others here) find a sparse, flat 
exception hierarchy to be problematic and limiting. But even with a rich

themselves to catching course-grained exceptions can do so, thanks to the 
nature of subtyping. So why are we even discussing this?
