eight looks interesting. But it took me 2 minutes to understand it was the name of the language. Maybe write it capitalized, "Eight". "eight" is quite confusing.
"Everything" is a closure, the 'leak idea, etc.: cool, interesting stuff!
I'm still waffling on 'Eight' or 'eight' --- in my notes I write it '8', which is even less clear ;)

And the qualitative feeling of programming in this language? Fullness. 'Cause you just Eight.
