Sorry, I wasn't clear enough. I'm not asking for non-rollback behaviour.
I was trying to say that _IF_ one ever needs to "SET" stuff that can't be
rolled back then it may be better to use some other keyword for that feature.
I'm actually for #1 SET being rolled back and to not have any "Oracle
behaviour" settings at all. Anything that can't be rolled back shouldn't
use SET.
