Apologies. I was assuming a matching:

- (NSObject *)foo{
  return foo;
}

But, if you always write:

- (NSObject *)foo{
  return [[foo copy] autorelease];
}

then my "swap" criticism doesn't apply. However, I often want access to 
an object's part, not a transient copy of the part. (When I pull a 
puppet's string, connected to its finger, I expect the finger to move, 
not a copy of the finger, which is then immediately thrown away.)
