after How to check if an object is an object of arguments in JavaScript?

None of the proposed solutions work in IE8. Is there a way to determine if an object is an object of arguments in IE8?

@Rocket and @cliffs_of_insanity are correct, I had to test incorrectly at first.

All together I came:

var isArguments = function(obj) { return (obj != null) && // since undefined == null ((Object.prototype.toString.call(obj) == '[object Arguments]') || (!!obj.callee)); // fixes for ie8 non-strict-mode };
