LanguageFeatures/Constant-update-2018/ShortCircuitOperators_A01_t12 is wrong

 tests/co19_2/src/LanguageFeatures/Constant-update-2018/ShortCircuitOperators_A01_t12.dart:23:34: Error: A value of type 'Type' can't be assigned to a variable of type 'bool'.
  - 'Type' is from 'dart:core'.
   const MyClass() : b = false && nil;
                                  ^
const nil = Null;

class MyClass {
  final bool b;
  const MyClass() : b = false && nil;
}

main() {
  const res = MyClass();
}

Maybe const nil = Null;was meant to be const nil = null; (note the lowercase 'N')?
