In the April session, Steven touched on his thoughts regarding where to handle exceptions (briefly: as close as possible to where it was raised). This conflicts with Tom Kyte's position that you should let the exception propagate up to the outermost block and then handle exceptions there. Tom can't speak for himself, but Steven is sure others will chime in.
