There are some cases that `named_struct` makes arguably more pretty when they are internally used. For example: ```diff -| org.apache.spark.sql.catalyst.expressions.ZipWith | zip_with | SELECT zip_with(array(1, 2, 3), array('a', 'b', 'c'), (x, y) -> (y, x)) | struct<zip_with(array(1, 2, 3), array(a, b, c), lambdafunction(named_struct(y, namedlambdavariable(), x, namedlambdavariable()), namedlambdavariable(), namedlambdavariable())):array<struct<y:string,x:int>>> | +| org.apache.spark.sql.catalyst.expressions.ZipWith | zip_with | SELECT zip_with(array(1, 2, 3), array('a', 'b', 'c'), (x, y) -> (y, x)) | struct<zip_with(array(1, 2, 3), array(a, b, c), lambdafunction(struct(namedlambdavariable(), namedlambdavariable()), namedlambdavariable(), namedlambdavariable())):array<struct<y:string,x:int>>> | ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
