Description André Bargull 2013-02-04 15:58:13 PST

See ECMAScript 5.1 [13.2.3] "The [[ThrowTypeError]] Function Object", the [[Extensible]] internal property of the [[ThrowTypeError]] is set to `false`. 

test case:
---
(function() {
  var throwTypeError = Object.getOwnPropertyDescriptor(function(){"use strict"}, "caller").get;
  return Object.isExtensible(throwTypeError);
})()
---

Actual: `Object.isExtensible(throwTypeError)` returns `true`
Expected: `Object.isExtensible(throwTypeError)` returns `false`
