Um ... design sanity and consistency, maybe? Not that I think PL/SQL
is any paragon of those virtues, but surely "we'll invent any feature
we feel like whether it's sane or not" is not a recipe for a
maintainable language.
(No, I'm not particularly in favor of the BY feature mentioned upthread,
either.)
