I suppose you haven't redeclared your ivars as "modern"-style properties (using
`@property` syntax), huh? I'd recommend taking the time to do so. This will
make ownership obvious (via the `strong`/`weak` keywords) and you'll get the
appropriate retention by just assigning to the property. It'll also let you
delete vast swaths of boilerplate accessor code (presuming your code base is of
the vintage I'm guessing it is).
