This is very promising. Because of my dissatisfaction with 
existing editor tooling, I had been working on a VS Code 
extension based around DMD, with its JSON output as the 
foundation. But using DMD as a library seems like a much better 
way. Since yours works on Windows now, I'm looking forward to 
trying it more extensively (and maybe I can ditch my own 
extension).
