    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.
