I was looking over some of the init and encode methods you have, there are a few bits that might need some touch ups to match behavioral differences but I think I can probably merge in some of the work I have done as an addendum to what you have already gotten done.

It might be good for review side of things to break out those other issues into their own pull requests. Is there a reason to implement NSLog and not just use print?

SR-380; that is a compiler issue? or runtime?

 NSArchiver is old and not very cross platform on the darwin side of things anyhow. I think we should just focus on NSCoder/NSKeyedArchiver and user subclasses of each case.

Have you tested yet on ubuntu?
