Is there any plan to support lambda expressions (the

x -> expression

syntax) within generated column definitions. Running a query like below throws an error

mysql> CREATE TABLE your_table (
    ->     id INT,
    ->     original_payload_array ARRAY<VARCHAR(100)>,
    ->     lowered_payload_array ARRAY<VARCHAR(100)> AS array_map(x -> lower(x), original_payload_array)
    -> )
    -> DISTRIBUTED BY HASH(id);
ERROR 1064 (HY000): Getting analyzing error. Detail message: can not get column by column id: x.
