The main challenge I see here is that all `ExprSchemable` methods have signatures like ``` fn get_type(&self, schema: &dyn ExprSchema) -> Result<DataType>; ``` the result of the method is dependent on the `schema` argument. As a consequence you need to use that to validate the usability/correctness of the memorised result. In the proposed `ExprProperties` solution, I'm not sure how you would be able to do that. -- This is an automated message from the Apache Git Service.
