There, I knew there was a good reason not to use it! Thanks, I just couldn't remember it for the life of me.

  Perhaps this would be faster?
  
  -setFriend:(id)aFriend
  {
  if (aFriend != friend)
  {
  [friend release];
  friend = [aFriend retain];
  }
  }
  
  I suppose it depends on the efficency of the comparison operation.

  I believe the PPC's branch prediction is good enough to make that fast, but faster still will probably be:
  
  -(void)setFriend:(id)aFriend
  {
  [aFriend retain];
  [friend release];
  friend = aFriend;
  }
  
  Which avoids the releasing problem. But keep in mind that this is all subjective, I have done absolutely no tests of efficiency regarding these.
