michael@0:    ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
michael@0:    Description:
michael@0:    Every execution context has associated with it a scope chain. This is
michael@0:    logically a list of objects that are searched when binding an Identifier.
michael@0:    When control enters an execution context, the scope chain is created and
michael@0:    is populated with an initial set of objects, depending on the type of
michael@0:    code. When control leaves the execution context, the scope chain is
michael@0:    destroyed.
michael@0: 
michael@0:    During execution, the scope chain of the execution context is affected
michael@0:    only by WithStatement. When execution enters a with block, the object
michael@0:    specified in the with statement is added to the front of the scope chain.
michael@0:    When execution leaves a with block, whether normally or via a break or
michael@0:    continue statement, the object is removed from the scope chain. The object
michael@0:    being removed will always be the first object in the scope chain.
michael@0: 
michael@0:    During execution, the syntactic production PrimaryExpression : Identifier
michael@0:    is evaluated using the following algorithm:
michael@0: 
michael@0:    1.  Get the next object in the scope chain. If there isn't one, go to step 5.
michael@0:    2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
michael@0:    the property.
michael@0:    3.  If Result(2) is true, return a value of type Reference whose base object
michael@0:    is Result(l) and whose property name is the Identifier.
michael@0:    4.  Go to step 1.
michael@0:    5.  Return a value of type Reference whose base object is null and whose
michael@0:    property name is the Identifier.
michael@0:    The result of binding an identifier is always a value of type Reference with
michael@0:    its member name component equal to the identifier string.
