How do you think it stands up to Carbon?
Carbon, on the other hand, is just Google code standard as a frontend. No exceptions, weird naming schemes etc. It's like a coding guideline made language. The guys behind it clearly know performance though, so I am not saying it won't be that. But will it be a great language? I don't think it can compete with what Herb Sutter is trying to achieve. I am of course willing to be proven wrong.
