I think Go is very interesting. One thing that I like about Go is something for which it is often criticized, which is the ability to create a binary that holds all dependencies. Some people are critical of these "fat binaries", but I have lost countless hours dealing with dependency issues, in various languages, and dependency issues are my least favorite kind of computer problem, so any language (and/or eco-system) that gives me an easy way to solve dependency problems is interesting. Likewise, when I work in Clojure I often go with the "uberjar" option to deploy, which often means the only outside dependency is the JVM itself. But Go can go further, as there is no need for some VM, like the JVM.
I agree, shipping the dependencies in a single binary is the easiest way to package software. Nim is the same as Go in this respect: native code generation via compilation to C without a VM. And for me, Nim's Pythonic syntax is hands down more pleasant than Go's or even D's. It's the only systems programming language I've come across where it feels like I'm coding at the speed of thought.
I haven't heard much about Nim (until reading this post). I saw that someone was comparing it to python in a way? What are your thoughts on it?
