Misty: Programing Language from the Creator of JSON (crockford.com)

Now I'm waiting for Brendan Eich's book "Misty: the good parts"

I’m not sure it’s possible to create a less intuitive, enticing or understandable landing page for a language than this.

According to one of Crockford's recent talks, it's called Misty because it's vaporware for now. But it's similar to another language called Neo which he wrote about in his last book and also provided source code for.
