C++ interop

[Laeeth]

I guess you should mention extern(C++). You can use dpp to #include C++ headers if you blacklist STL and Boost types and it will work for quite a lot. It's still not complete yet but it keeps getting better and in a year or two STL should be fine. It's used in production but it's not something I would say is easy for just anyone to use and expect to work immediately. For C++ - C mostly just works.

Can you do that now using Nim? Just include c++ headers and use them?

How about generating c++ headers from Nim code? We do that in D but the available options aren't yet polished.
