Any significant change to the language is certainly going to take time and careful attention, so I'm not surprised the guilds and typing stuff hasn't fully seen the light of day at this point. Performance progress is certainly welcome...while I applaud the goal of 3x speed over Ruby 2.0, I'd be quite content with only 2x, which I suspect is a more realistic target.
