Description Oliver Hunt 2009-08-14 03:40:47 PDT 
ES5 says that the Arguments should inherit from array (Section 10.6).  Specifically that construction of the Arguments object is as follows (assuming Object and Array are the standard builtin Object and Array objects, and that their prototypes are unchanged):

obj = new Object with the class Arguments
obj.__proto__ = Array.prototype
obj.constructor = Object
obj.toString = Object.prototype.toString
obj.toLocalString = Object.prototype.toLocaleString

You seem to be checking in another mozilla test failing?  If so, is this intentional, could you not just fix the test?
