+/**
+ File Name: 10.1.8-2
+ ECMA Section: Arguments Object
+ Description:
+
+ When control enters an execution context for declared function code,
+ anonymous code, or implementation-supplied code, an arguments object is
+ created and initialized as follows:
+
+ The [[Prototype]] of the arguments object is to the original Object
+ prototype object, the one that is the initial value of Object.prototype
+ (section 15.2.3.1).
+
+ A property is created with name callee and property attributes {DontEnum}.
+ The initial value of this property is the function object being executed.
+ This allows anonymous functions to be recursive.
+
+ A property is created with name length and property attributes {DontEnum}.
+ The initial value of this property is the number of actual parameter values
+ supplied by the caller.
+
+ For each non-negative integer, iarg, less than the value of the length
+ property, a property is created with name ToString(iarg) and property
+ attributes { DontEnum }. The initial value of this property is the value
+ of the corresponding actual parameter supplied by the caller. The first
+ actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
+ so on. In the case when iarg is less than the number of formal parameters
+ for the function object, this property shares its value with the
+ corresponding property of the activation object. This means that changing
+ this property changes the corresponding property of the activation object
+ and vice versa. The value sharing mechanism depends on the implementation.
