> The codegen output of {{Expression}}, {{ExprCode}}, now encapsulates only strings of output value ({{value}}) and nullability ({{isNull}}). It makes difficulty for us to know what the output really is. I think it is better if we can add wrappers for the value and nullability that let us to easily know that.
