IMO this is almost a no-brainer. ARC is not a full garbage collector. So the garbage collector algorithm already needs to be clever about what it's doing. I've written a very basic dynamic memory allocation class which ensures that any dynamically allocated memory is automatically deallocated when the program ends, essentially providing a basic garbage collection feature. This brings me to one of the more controversial features of high level languages: garbage collection. Perhaps this was a decent reaction to the memory management of C, but as a whole, in general purpose languages, garbage collection is more of a detriment than a benefit. JavaScript is a garbage collected language, which means developers generally don't have to worry about memory management, unlike lower level programming languages. The last example with circular reference To ensure fast object allocation, short garbage collection pauses, and no memory fragmentation V8 employs a stop- the-world, generational, accurate, garbage collector. This means that V8: stops program execution when . I'm not sure if this is worthwhile to build.). ARC occupies a middle ground between garbage collection and manual memory management. In the latter case, new causes the class' constructor to be called automatically. Like garbage collection, ARC frees the programmer .. Good location in memory, and secondly preventing a degradation in layout when the RDS automatic solution in some languages is to use a 'layout-improving' garbage collector, aware RDSs and layout-improving garbage collectors. Furthermore, the simplified model requires hiding the true nature of memory making it more difficult to implement certain inter-process and concurrent programming algorithms. Right now it doesn't, but in theory it could fall back to the dynamic subclass craziness for those classes. Conclusion Automatic reference counting substantially reduces the burden on the programmer for dealing with memory management.
