I have written a bit of Go. It strikes me as sort of the Unix of programming languages. It's very opinionated, takes some overarching concepts, mostly channels and interfaces, then proceeds to thoroughly not care what you think about it: refuses to have generics, lambdas and tail-call recursion like a pro. The polar opposite of design by committee. It even enforces a True Brace Style to keep the parser simple!

Technically, it looks good to me. The toolchain is excellent. It looks ready for production. Programming in it is fun. It fixes most issues of compiled languages. Go has mostly replaced Haskell, for me.
