23    File Name:          10.2.2-1.js
24    ECMA Section:       10.2.2 Eval Code
25    Description:
26
27    When control enters an execution context for eval code, the previous
28    active execution context, referred to as the calling context, is used to
29    determine the scope chain, the variable object, and the this value. If
30    there is no calling context, then initializing the scope chain, variable
31    instantiation, and determination of the this value are performed just as
32    for global code.
33
34    The scope chain is initialized to contain the same objects, in the same
35    order, as the calling context's scope chain.  This includes objects added
36    to the calling context's scope chain by WithStatement.
37
38    Variable instantiation is performed using the calling context's variable
39    object and using empty property attributes.
40
41    The this value is the same as the this value of the calling context.
