Not sure about this one.

Changed to expect static warning (together with 07, 10).

+
+  noSuchMethod(_) => null; /// 03: ok
+  method3(); /// 03: continued
+
+  noSuchMethod(_, [__]) => null; /// 04: ok
+  method4(); /// 04: continued
+
+  noSuchMethod(_); /// 05: ok
+  method5(); /// 05: continued
+
+  noSuchMethod(_) => null; /// 08: continued
+
+  noSuchMethod(_) => null; /// 11: continued
+}
+
+@proxy /// 12: static type warning
+class B {
+  method12(); /// 12: continued
+
+  noSuchMethod(_) => null; /// 13: static type warning
+  method13(); /// 13: continued
+}
+
+class Class2 extends B {
+}
+
+main() {
+  new Class1();
