@autoreleasePool { [[[SomeObject alloc] init] autorelease]; }//someobject is release after exiting this scope

//inside main runloop, not inside @autorelease{} [[[AnotherObject alloc] init] autorelease];

//AnotherObject will be release at end of main runloop

[[NotAutoreleased alloc] init]; //will leak past runloop iteration

is that understanding correct?
