The real benefit of this language, over other formal languages is the focus on being able to write real programs in it. Most theorem proving languages are focused on mathematics or proving things about a program, and they are very abstract. This language appears to have a goal of bridging the gap and making it simple to write programs and prove parts of them. I believe this…

Man, back when I did F# for a living, I really really wanted to use this for production, but I could never quite get sign-off.
