/**
   File Name:          regexp-enumerate-001.js
   ECMA V2 Section:
   Description:        Regression Test.

   If instance Native Object have properties that are enumerable,
   JavaScript enumerated through the properties twice. This only
   happened if objects had been instantiated, but their properties
   had not been enumerated.  ie, the object inherited properties
   from its prototype that are enumerated.

   In the core JavaScript, this is only a problem with RegExp
   objects, since the inherited properties of most core JavaScript
   objects are not enumerated.
