 // AcceptLanguageList  // Implementation Notes:
   // =====================
   //
   // The internal representation member (_rep) is a pointer to an
   // AcceptLanguageListRep object. We could define a class with this name
   // as follows:
   //
   //     class AcceptLanguageListRep
   //     {
   //         AcceptLanguageArray array;
   //     };
   //
   // But this requires separate heap object to hold the array. Instead we use
   // the following fact to eliminate the extra heap object:
   //
   //     sizeof(AcceptLanguageArray) == sizeof(AcceptLanguageListRep*)
   //
   // We know this since all arrays contain a single pointer to a representation
   // object. Take for example the following structure:
   //
   //     class MyClass
   //     {
   //         void* rep;
   //     };
   //
   // Clearly, sizeof(MyClass) == sizeof(void*). We eliminate the extra heap object
   // by overlaying the AcceptLanguageList::_rep pointer with the array base. So
   // AcceptLanguageList::_rep in fact refers to the Array<T>::_rep.
 // //
