+/**
+ File Name: 10.2.2-1.js
+ ECMA Section: 10.2.2 Eval Code
+ Description:
+
+ When control enters an execution context for eval code, the previous
+ active execution context, referred to as the calling context, is used to
+ determine the scope chain, the variable object, and the this value. If
+ there is no calling context, then initializing the scope chain, variable
+ instantiation, and determination of the this value are performed just as
+ for global code.
+
+ The scope chain is initialized to contain the same objects, in the same
+ order, as the calling context's scope chain. This includes objects added
+ to the calling context's scope chain by WithStatement.
+
+ Variable instantiation is performed using the calling context's variable
+ object and using empty property attributes.
+
+ The this value is the same as the this value of the calling context.
