> Go has a rich standard library which covers a lot of areas.

The last time I've looked at it there wasn't queue, deque, stack libraries in standard library. There wasn't even a UUID library. I'm not sure if it has these libraries in 1.1.

Python has a built-in HTTP server (including a CGI one too).

How does Go make it easier than those unnamed languages? Go didn't even have race detection tool until 1.1.
