ARC does change the way you write code. It tries to turn Objective-C into a "magic" language to satisfy people used to garbage collection, or people who trust the compiler to do the right thing. As we discussed at devmeeting 2013, my personal reasons for not trusting ARC are admittedly irrational: I was bit by GC many years ago, and one of the reasons why I approached Objective-C was that refcounting was consistently present, consistently ubiquitous and publicly exposed. ARC hides it. I don't like hidden reference counting. > > And five years from now, any arguments against naming it relative to > Objective-C 2.0 will stand against naming it Objective-C+ARC or similar. > > If our web site is still saying the same thing in five years, then we have > other problems. > Let's compose something that makes it irrelevant if we change the website or not. Let's compose something that doesn't depend on one specific feature. First big changes in the language came with what was called Objective-C 2.0. There is no need to invent our own point in time where the changes started to happen and where it is important to point out that we support post-1990s things. At this point I think I gave enough input and will drop the subject.
