Right. But I don't like the notion of making SET's behavior vary
depending on context. I think it's better both from a user-friendliness
standpoint and from a compatibility standpoint to use different syntaxes
to indicate the desired behavior.

Well, if you accept the notion of distinguishing it by syntax, then
we're down to arguing about which case should be associated with the
existing syntax. And I think persistent has to win on compatibility
grounds. (Doesn't the Perl DBI driver also do the automatic-begin
thing? Breaking all Java apps and all Perl apps that issue SETs is
rather a big compatibility problem IMHO...)
