42 ECMA Section: 10.2.2 Eval Code
45 When control enters an execution context for eval code, the previous
46 active execution context, referred to as the calling context, is used to
47 determine the scope chain, the variable object, and the this value. If
48 there is no calling context, then initializing the scope chain, variable
49 instantiation, and determination of the this value are performed just as
52 The scope chain is initialized to contain the same objects, in the same
53 order, as the calling context's scope chain. This includes objects added
54 to the calling context's scope chain by WithStatement.
56 Variable instantiation is performed using the calling context's variable
57 object and using empty property attributes.
59 The this value is the same as the this value of the calling context.
