I like both Haskell and Rust (in theory; haven't written anything nontrivial in either). But they both seem to encourage you to spend a lot of time and energy on the meta aspects of programming. You can build safe, beautiful systems, but you can also happily spend all day (all week? all month?) playing various forms of code golf without actually producing anything. Go, like C, is a very get-it-done language. It doesn't let you have any fun at all with abstractions, so you end up just doing your work instead. In spite of its warts, I think Go is remarkable and unique for this quality.
