That said, I have been doing some followup. Here is some of it: because packages o break the dependency chain (no cascading invalidations when you install a new package body -- if you have procedures that call procedures -- compiling one will invalidate your database) o support encapsulation -- I will be allowed to write MODULAR, easy to understand code -- rather then MONOLITHIC, non-understandable procedures o increase my namespace measurably. package names have to be unique in a schema, but I can have many procedures across packages with the same name without colliding o support overloading o support session variables when you need them o promote overall good coding techniques, stuff that lets you write code that is modular, understandable, logically grouped together.... So far that's all "that'd be nice, but isn't a technical barrier" stuff. Package variables for example. When _do_ you _need_ them? For what? (I'm aware of some uses but "when you need them" helps us not at all).
