> Spark today allows overloading between persisted relations and function and temporary relations and functions.
> It also allows overloading between persisted functions and builtin functions.
> While Spark allows us to disambiguate a persisted objects by qualifying it, there is no qualifier for temp or builtin objects.
> Here we propose to use `builtin` for builtin objects and `session` for session temporary objects.
> If there is a conflict with persisted schemas of this name we can further declare that the catalog for both is `system`
