Very cool to see this gaining traction, my favourite hedgefonds-I-never-got-to-work-at introduced D to me and I believe it's one of the more interesting projects in languages right now.
Sure, that's what makes C++ one of the worst PLs. Just break for every decade or so to fix things for good.
What's D been doing meanwhile? D community and the authors know its short comings for over a decade now, which are the reasons for its lack of adoption even in the open source world. Most of the D code is yet to be written, tbh. If D can't break stuff to fix the mistakes with defaults, why was all the hatred marketing towards C++? Was it a failed strategy trying to kill C++, so let's just surrender to it via core.stdcpp?
PS: Yes, D has the best interop with C++ in the world and even better interop with C as the memory model is same!
