     24     ECMA Section:       11.2.1 Property Accessors
     25     Description:
     26 
     27     Properties are accessed by name, using either the dot notation:
     28                                 MemberExpression . Identifier
     29                                 CallExpression . Identifier
     30 
     31     or the bracket notation:    MemberExpression [ Expression ]
     32                                 CallExpression [ Expression ]
     33 
     34     The dot notation is explained by the following syntactic conversion:
     35                                 MemberExpression . Identifier
     36     is identical in its behavior to
     37                                 MemberExpression [ <identifier-string> ]
     38     and similarly
     39                                 CallExpression . Identifier
     40     is identical in its behavior to
     41                                 CallExpression [ <identifier-string> ]
     42     where <identifier-string> is a string literal containing the same sequence
     43     of characters as the Identifier.
     44 
     45     The production MemberExpression : MemberExpression [ Expression ] is
     46     evaluated as follows:
     47 
     48     1.  Evaluate MemberExpression.
     49     2.  Call GetValue(Result(1)).
     50     3.  Evaluate Expression.
     51     4.  Call GetValue(Result(3)).
     52     5.  Call ToObject(Result(2)).
     53     6.  Call ToString(Result(4)).
     54     7.  Return a value of type Reference whose base object is Result(5) and
     55         whose property name is Result(6).
     56 
     57     The production CallExpression : CallExpression [ Expression ] is evaluated
     58     in exactly the same manner, except that the contained CallExpression is
     59     evaluated in step 1.
