Go turns three
We've been playing around with Go where I work. The concurrency model is great, and the type/object/interface approach is pretty flexible. The language designers also succeeded in eliminating many of the pain points they felt with C/C++/Java: dependency bloat and compilation speed. My workflow with Go has more in common with an interpreted language than anything else.However, the lack of generics seems like a pretty bad oversight. It's annoying to rewrite common functional operations (e.g. map, reduce) over and over again  with slightly different argument types (or sprinkling type casts all over your code).
