Simul CTE

[KyGost]

Some kind of witchcraft within #106 has made it such that simultaneous CTEs work?

Test fails:

glue.execute(
			r#"
		WITH cte_0 AS (
			SELECT
				a
			FROM
				cte_1
		), cte_1 AS (
			SELECT
				a
			FROM
				basic
		)
		SELECT
			a
		FROM
			cte_0
	"#,
		)
		.expect_err("CTE is not simultaneous");
