> It would be nice to be able to UNNEST an array of structs. For example:
> {code:sql}
> WITH pcol AS
>   (SELECT 1 AS key, ARRAY[STRUCT("abc" AS name, "rst" AS slot),STRUCT("def" AS name, "uvw" AS slot)] AS promo
>   UNION ALL
>   SELECT 2 AS key, ARRAY[STRUCT("ghi" AS name, "xyz" AS slot)] AS promo)
> SELECT * FROM pcol, UNNEST(pcol.promo);
> {code}
