Review Comment:
I think this is an edge case example
```sql
SELECT * from UNNEST([1,2,3]), UNNEST([1,2,3,4])
```
is transformed into
```sql
SELECT UNNEST(make_array(Int64(1),Int64(2),Int64(3))),
UNNEST(make_array(Int64(1),Int64(2),Int64(3),Int64(4))) FROM UNNEST([1, 2, 3])
AS unnset_table_1 (UNNEST(make_array(Int64(1),Int64(2),Int64(3)))) CROSS JOIN
UNNEST([1, 2, 3, 4]) AS unnset_table_1
(UNNEST(make_array(Int64(1),Int64(2),Int64(3),Int64(4))))
```
