Go

Go is a statically typed, compiled language with a dynamic and lightweight feel. With Go you get the efficiency benefits of being close to the machine–your programs compile to native code–with the productivity and quick turnaround of a scripting language.
Why do they keep saying it "feels" like a dynamic scripting language? I don't get a fraction of the compile-time I errors I get with Go when I write in C. It "feels" like a clusterfuck of a compiled language. What the fuck is lightweight about it? You don't have to call free? Big fucking deal. Stop comparing it to scripting languages.

It's displacing Javascript as the Ruby of curly-braced languages, not by market share, but by how unjustifiable its existence is, and how idiotic its fanboys are.
