Nit: I prefer separate tests that are more targeted:

B() : super.foo
        /*  /// 01: compile-time error
        ()
        */  /// 01: continued

Changed it.

+  : this.foo  /// 02: compile-time error
+  ;
+  B.foo();  /// 02: continued
 }
 
-main() {
-  new B();
-  if (!inConstructor) throw 'Test failed';
-}
+main() => new B();
