I'm not sure we should expect anything but handwaving. This language hasn't been released to the world; it may be that it's not even a fully-functional language yet. All we've got to go on is a couple sentences from a blog post that clearly wasn't intended as a detailed exposition, a G+ post from someone who is no longer involved in the project, and a whole lot of Reddit. Mostly the Reddit.

More details will hopefully be coming soon, but until then we might as well stay calm and try not to confuse cocktail napkins with something that's ready for peer review.
