> Currently, it is required to state column names when LATERAL VIEW is used.
> That shouldn't be necessary, since UDTF returns struct which contains column names - and they should be used by default.
> For example, it would be great if this was possible:
> SELECT t.*, t.key1 + t.key4
> FROM some_table
> LATERAL VIEW JSON_TUPLE(json, 'key1', 'key2', 'key3', 'key3') t;
