def _setup_orm_returning(self, compiler, orm_level_statement, dml_level_statement, use_supplemental_cols=True, dml_mapper=None): (source)

establish ORM column handlers for an INSERT, UPDATE, or DELETE which uses explicit returning(). called within compilation level create_for_statement. The _return_orm_returning() method then receives the Result after the statement was executed, and applies ORM loading to the state that we first established here.
