   5
   6     If instance Native Object have properties that are enumerable,
   7     JavaScript enumerated through the properties twice. This only
   8     happened if objects had been instantiated, but their properties
   9     had not been enumerated.  ie, the object inherited properties
  10     from its prototype that are enumerated.
  11
  12     In the core JavaScript, this is only a problem with RegExp
  13     objects, since the inherited properties of most core JavaScript
  14     objects are not enumerated.
