I had effectively changed `Expr::Scalar` to report its type as `DataType::Null` its interior `ScalarValue::is_null()` returned true. That seemed fairly promising but I got blocked by the lack of null cast kernels in Arrow. Now I think we have those kernels it would be useful to try again -- but I am not sure when I will have the time again -- This is an automated message from the Apache Git Service.
