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