    File Name:          11.2.1-5.js
    ECMA Section:       11.2.1 Property Accessors
    Description:

    Properties are accessed by name, using either the dot notation:
                                MemberExpression . Identifier
                                CallExpression . Identifier

    or the bracket notation:    MemberExpression [ Expression ]
                                CallExpression [ Expression ]

    The dot notation is explained by the following syntactic conversion:
                                MemberExpression . Identifier
    is identical in its behavior to
                                MemberExpression [ <identifier-string> ]
    and similarly
                                CallExpression . Identifier
    is identical in its behavior to
                                CallExpression [ <identifier-string> ]
    where <identifier-string> is a string literal containing the same sequence
    of characters as the Identifier.

    The production MemberExpression : MemberExpression [ Expression ] is
    evaluated as follows:

    1.  Evaluate MemberExpression.
    2.  Call GetValue(Result(1)).
    3.  Evaluate Expression.
    4.  Call GetValue(Result(3)).
    5.  Call ToObject(Result(2)).
    6.  Call ToString(Result(4)).
    7.  Return a value of type Reference whose base object is Result(5) and
        whose property name is Result(6).

    The production CallExpression : CallExpression [ Expression ] is evaluated
    in exactly the same manner, except that the contained CallExpression is
    evaluated in step 1.
