Merci Aikah :). I know Go yes. It is a nice platform for web programming. There are some good articles comparing Go and C++. I guess C++ will always be faster than Go, but Go may be a better choice for productivity, especially if you do not know C++. Compilation time also a big C++ problem.
In short, this framework is targeted to experienced C++ users with a big focus on performance.
In terms of language, the big difference to me between Go and C++ is templates. Go does not include them, which makes it a bit more limited but on the other hand much simpler to understand for beginners and faster to compile.
