 // Array.of does a strict assignment to the new object's .length.

 // The assignment is strict even if the code we're calling from is not strict.

 load(libdir + "asserts.js");

 function Empty() {}

 Empty.of = Array.of;

 Object.defineProperty(Empty.prototype, "length", {get: () => 0});

 var nothing = new Empty;

 nothing.length = 2;  // no exception; this is not a strict mode assignment

 assertThrowsInstanceOf(() => Empty.of(), TypeError);
