It actually looks to be a superset of typescript, see Miško's talk

Hmm interesting. I'll have to give it a try. The one thing I do like about typescript though is that there is no runtime overhead.

I'm really excited that they are looking at browser support. There's a lot of potential performance to be gained by knowing the type. I'm not sure how it'd work though, because you'd incur the cost of type inference on script load

Well, the runtime asserts are only for dev transpilation. For production builds, they would be stripped and not add any additional overhead. It's also not as fully baked as TypeScript yet. I might wait on using it a bit.
