That's very interesting, I didn't know that attribute existed. I imagine
that post-dates autorelease pools by some years. But most objects returned
by framework functions are autoreleased which means you can only get rid of
them by bracketing them with an autorelease pool. This bugs me somewhat and
is obviously less efficient than just throwing them away when you are done
with them. But it does let you pass @"string" as a function parameter I
suppose without having to release it afterwards. Still can't say I like it
much. Sorry if I hijacked the thread.
