I really don't like this approach.  It makes the code difficult to  
read, destroys locality of reference, and hurts performance.

Please, please, please, can other people test my non-fragile ivars  
patch so that we can get rid of ugly hacks like this and just not  
declare any ivars in the headers.  I posted it months ago and have had  
absolutely no reports of testing yet.
