This will report error in cypher.

Expressions related implementation changes should not change the Interface of the Validator.

need to rewrite the expression after fold into the mapexpression

  Scenario: toInteger
    When executing query:
      """
-      YIELD [toInteger(true), toInteger(false), toInteger(1), toInteger(3.14),


Why change this case?

toInteger(false), toInteger(true) will report error in opencypher, other modified cases too

I think you should keep the origin case, and add new one to test the origin function.

i know, but the result of origin case is wrong, and the modified logic test has been covered

LGTM. But, I have a small question. Is it reasonable to expose BAT_TYPE to users? I haven't learned about GQL and opencypher. If they are like this, that's OK. But if they are not like this, is it necessary for us to standardize the null type we return to user? After all, our Value has many kinds of null type.

Neither of them return BAD_TYPE, so the NULL, BAD_TYPE should be reconsidered

All bad nulls is actually just an error with an error message. It may be more reasonable to provide a Value overload with customizable error messages, bcz current expressions’ ability to report and transmit errors is very limited.
