I wish that all of these sort of efforts would be folded into GNUstep:

gnustep.org

and that we would arrive at something useful and easily installed and widely accepted.

They don't even support Objective-C latest, as GCC only supports what NeXT was obliged to upstream.

I'm pretty sure that's just the runtime.

Trivial to support. There is probably some AI slop for it. The main issue is providing an object platform people want to use.

Objective-C 2.0+ also has syntax and semantic updates, besides the whole weak references, and ARC improvements.
