I really like this too, but Barry's proposal doesn't really *break* anything. Existing Python code that creates a FooBar(Exception) and then catches it with either "except FooBar:" or "except Exception, e:" + check for FooBar, will still work as expected. At *worse*, it would be catching too much, like SystemExit or GeneratorExit, which are still pretty uncommon exception. OTOH, I also understand that people have been told that deriving from Exception is the right thing to do forever now.
