But this does not:

david=# DO $$
david$# BEGIN

david$#     PERFORM * FROM (
david$#         WITH inserted AS (
david$#             INSERT INTO foo values (1) RETURNING id
david$#         ) SELECT inserted.id
david$#     ) x;
david$# END;
david$# $$;
ERROR:  WITH clause containing a data-modifying statement must be at the top level
