+ File Name: 10.1.4-1.js
+ ECMA Section: 10.1.4 Scope Chain and Identifier Resolution
+ Description:
+ Every execution context has associated with it a scope chain. This is
+ logically a list of objects that are searched when binding an Identifier.
+ When control enters an execution context, the scope chain is created and
+ is populated with an initial set of objects, depending on the type of
+ code. When control leaves the execution context, the scope chain is
+ destroyed.
+
+ During execution, the scope chain of the execution context is affected
+ only by WithStatement. When execution enters a with block, the object
+ specified in the with statement is added to the front of the scope chain.
+ When execution leaves a with block, whether normally or via a break or
+ continue statement, the object is removed from the scope chain. The object
+ being removed will always be the first object in the scope chain.
+
+ During execution, the syntactic production PrimaryExpression : Identifier
+ is evaluated using the following algorithm:
+
+ 1. Get the next object in the scope chain. If there isn't one, go to step 5.
+ 2. Call the [[HasProperty]] method of Result(l), passing the Identifier as
+ the property.
+ 3. If Result(2) is true, return a value of type Reference whose base object
+ is Result(l) and whose property name is the Identifier.
+ 4. Go to step 1.
+ 5. Return a value of type Reference whose base object is null and whose
+ property name is the Identifier.
+ The result of binding an identifier is always a value of type Reference with
+ its member name component equal to the identifier string.
