WebKit strict mode bugs

WebKit-strict-mode.js

// WebKit strict mode bugs

// Eval code should be "strict eval code" if the call to eval is a direct call (15.1.2.1.1) to
// the eval function that is contained in strict mode code:
(function () {
  "use strict";
  return eval('(function() { return !this; })()');
})();


// Function code that is supplied as the last argument to the built-in Function constructor is
// "strict function code" if the last argument is a String that when processed as a FunctionBody
// begins with a Directive Prologue that contains a Use Strict Directive:
Function('"use strict"; return !this;')();


// The `this` value should be set to `undefined`, not to `null`, when a function call is made to
// a "not reference" or to a "non-property reference" (11.2.3):
(function(){"use strict"; return this === undefined; })();


// WebKit r69618 (running on Windows 7 x64) completely crashes, while a TypeError exception
// would be expected:
try { 
  (function () {"use strict"; this.foo;})();
} catch (e) {
  alert(e instanceof TypeError);
}

// This should be a ReferenceError, not an early reported SyntaxError:
(function () {"use strict"; foo = "bar";})();
