perhaps we can make an 'official' branch on anarki, one that would be guided by pg. so that if he says "add forward closures" or "implement a basic math library" the anarkists can go ahead and do that. because a lot of these features aren't exactly simple or quick to implement, so it may be better to just let pg be the overseer on a lot of them
No, there is not an 'official' one on anarky - that's the point. The only official one is Arc2.tar, and I wouldn't expect the next release anytime soon.
That's a good idea, and I think that will eventually be how it will work. But I think it's too early for that : obviously, he wants to completely design & implement the core functions (alone) before working (and let other work) on libraries.
