On: A nice, little known C feature: Static array indices in parameter declarations

[redial]

I believe the @ is used only by the obj-c keywords and not the ones from C. So it'll be something more like this

    @autoreleasepool{
        for (int index = 0; index < 100; index++){
            int error = [MyObject performSelector:@selector(addCoolFilterToImage:)];
            if (error) {
                return 32;
            }
        }
    }

Yeah, that was kind of my point.
