Does this take significantly longer to compile than regular C# code (I can't imagine the answer is no)? If so, it doesn't really address the concerns Go's implementors brought up, which precisely revolved around the compile time : runtime performance tradeoffs that the JIT compiler helps mitigate for C#'s generics.
