Add a test with constructor that takes arguments normally (via parameters)

+      self = this;
+      args = arguments;
+    }
+  }
+  class Derived extends Base {}
+
+  new Derived;
+  assertEquals(0, args.length);
+
+  new Derived(0, 1, 2);
+  assertEquals(3, args.length);
+  assertTrue(self instanceof Derived);
+
+  var arr = new Array(1e5);
+  var obj = {};
+  Derived.apply(obj, arr);
+  assertEquals(1e5, args.length);
+  assertEquals(obj, self);
+})();
