What if I have a [] operator that does something unusual to extract the
data from the object... for instance, a bitfield...

// interface parts only...
class packedbits 
{
 public:
  packedbits(int size);
  int operator[](int index);
  void set(int index);
  void clear(int index);
};

doit() 
{
   packetbits flags(100);

   if (flags[4])	// this works
     ....

   flags.set(4);	// works--but ugly
   flags[4] = 1;	// how can I make this work???
}
