I never thought of it, mainly because I've never seen it anywhere.

But I did quickly glance and it and it looks very interesting. Although I will take a closer look to see how active the community is, and the documentations too.

Thank you for the recommendation.

Just come here to say the same thing. D is a natural successor to C and C++, the only main thing that it lacks at the moment is the adoption and popularity.

Personally I think D is not only suitable for systems programming but it also very much suitable for modern data science programming as I commented recently in the other discussions on C++ Matlab like library topic [1].
