Of course there is almost nothing, which you cannot possibly do in any other language. The question is, at which effort and the resulting program quality. Go gives you strict (vs C) static type checking. Its local type inferencing saves you a lot of typing (as in keyboard) and makes the code concise and thus readable. It has a proper package system and very fast compile times (for larger projects way faster than C and C++). It has a rather rich standard library, it has a great GC which gets even better in 1.8 (100 microsecond stop times).
