Lack of autorelease optimization under ARC compiler

Question

I was just wondering, why is there no autorelease pool optimization under the ARC compiler, where it would retain an object in the innermost scope, remove it from the autoreleas

Answer 1

You could probably break the functionality up into multiple calls which would give the code time to breath. Like having a method do x at a time, and when that method returned it would likely release that memory.
