Hm, of is never called in this test?

+
+// The assignment is strict even if the code we're calling from is not strict.
+
+function Empty() {}
+Empty.of = Array.of;
+Object.defineProperty(Empty.prototype, "length", {get: function() { return 0; }});
+
+var nothing = new Empty;
+nothing.length = 2;  // no exception; this is not a strict mode assignment
