/** 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.
