 main() {
   // FutureOr<T> should be treated like `dynamic`. Dynamically the `T` is
   // completely ignored. It can be a malformed type.
   Expect.isTrue(499 is FutureOr<A>);
-  Expect.isTrue(499 is FutureOr<Does<Not<Exist>>>); // //# 00: static type warning
-  Expect.isTrue(499 is FutureOr<A, A>); //             //# 01: static type warning
 
   var a = new A();
   Expect.isTrue(a.toString() is String);
