michael@0:    ECMA Section:       11.2.1 Property Accessors
michael@0:    Description:
michael@0: 
michael@0:    Properties are accessed by name, using either the dot notation:
michael@0:    MemberExpression . Identifier
michael@0:    CallExpression . Identifier
michael@0: 
michael@0:    or the bracket notation:    MemberExpression [ Expression ]
michael@0:    CallExpression [ Expression ]
michael@0: 
michael@0:    The dot notation is explained by the following syntactic conversion:
michael@0:    MemberExpression . Identifier
michael@0:    is identical in its behavior to
michael@0:    MemberExpression [ <identifier-string> ]
michael@0:    and similarly
michael@0:    CallExpression . Identifier
michael@0:    is identical in its behavior to
michael@0:    CallExpression [ <identifier-string> ]
michael@0:    where <identifier-string> is a string literal containing the same sequence
michael@0:    of characters as the Identifier.
michael@0: 
michael@0:    The production MemberExpression : MemberExpression [ Expression ] is
michael@0:    evaluated as follows:
michael@0: 
michael@0:    1.  Evaluate MemberExpression.
michael@0:    2.  Call GetValue(Result(1)).
michael@0:    3.  Evaluate Expression.
michael@0:    4.  Call GetValue(Result(3)).
michael@0:    5.  Call ToObject(Result(2)).
michael@0:    6.  Call ToString(Result(4)).
michael@0:    7.  Return a value of type Reference whose base object is Result(5) and
michael@0:    whose property name is Result(6).
michael@0: 
michael@0:    The production CallExpression : CallExpression [ Expression ] is evaluated
michael@0:    in exactly the same manner, except that the contained CallExpression is
michael@0:    evaluated in step 1.
