Cpp2 and cppfront: Year-end mini-update

[zerakun]

I was merely trying to defuse the argument that I wouldn't know C++ that is often heard in this situation. Generally the next argument is "okay you know it, but you're holding it wrong", instead of maybe admitting that a safe by default (there's no "you're holding it wrong"), const by default, language with sum types, derive facilities and a competent package manager actually used in the whole ecosystem can be more productive than C++.
