1.11 + File Name: 10.1.8
1.12 + ECMA Section: Arguments Object
1.13 + Description:
1.14 +
1.15 + When control enters an execution context for declared function code,
1.16 + anonymous code, or implementation-supplied code, an arguments object is
1.17 + created and initialized as follows:
1.18 +
1.19 + The [[Prototype]] of the arguments object is to the original Object
1.20 + prototype object, the one that is the initial value of Object.prototype
1.21 + (section 15.2.3.1).
1.22 +
1.23 + A property is created with name callee and property attributes {DontEnum}.
1.24 + The initial value of this property is the function object being executed.
1.25 + This allows anonymous functions to be recursive.
1.26 +
1.27 + A property is created with name length and property attributes {DontEnum}.
1.28 + The initial value of this property is the number of actual parameter values
1.29 + supplied by the caller.
1.30 +
1.31 + For each non-negative integer, iarg, less than the value of the length
1.32 + property, a property is created with name ToString(iarg) and property
1.33 + attributes { DontEnum }. The initial value of this property is the value
1.34 + of the corresponding actual parameter supplied by the caller. The first
1.35 + actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
1.36 + so on. In the case when iarg is less than the number of formal parameters
1.37 + for the function object, this property shares its value with the
1.38 + corresponding property of the activation object. This means that changing
1.39 + this property changes the corresponding property of the activation object
1.40 + and vice versa. The value sharing mechanism depends on the implementation.
