FWIW, D is a language. I would not advocate for or against 
anything. But the
highest chance of success for languages is compatibility to 
consume the old
code bases, that for sure, at least in the big picture.

- Kotlin -> compatible with Java
- Swift -> interoperable with Objective-C
- C -> C++

I did not see a clean-cut language that got popular yet for real 
use in a considerable amount of places. Namely, compatibility is 
a feature. How deep is the big question and the devil is in the 
details: source-compatible? API/ABI? Etc. but throwing away and 
rewriting is not even realistic.
