Compared with? My reference point is python,java,clojure,c,c++. Python is huge and useful but messy and inconsistent. Java is huge and doesn't compose well. Clojure is underdocmented and hardly batteries included. C and C++ can't do anything useful without a bunch of extra libraries. From what I can see, C# is like java in this regard.

Go is a small incredibly useful and composable set of libraries that handles a vast amount of cases with a small amount of code.
