-// Test that hidden native exception classes can be marked as existing.
-//
-// To infer which native hidden types exist, we need
-//   (1) return types of native methods and getters
-//   (2) argument types of callbacks
-//   (3) exceptions thrown by the operation.
-//
-// (1) and (2) can be achieved by having nicely typed native methods, but there
-// is no place in the Dart language to communicate (3).  So we use the following
-// fake body technique.
-
-
-// The exception type.
-class E native "*E" {
-  E._used() native;  // Bogus native constructor, called only from fake body.
-
-  final int code;
-}
-
-// Type with exception-throwing methods.
-class A native "*A" {
-  op(int x) native {
-    // Fake body calls constructor to mark the exception class (E) as used.
-    throw new E._used();
-  }
-}
-
-// This class is here just so that a dynamic context is polymorphic.
-class B {
-  int get code() => 666;
-  op(String x) => 123;
-}
