To my surprise, a paper I wrote quite a while ago was on the front page of Hacker News this morning:

I started using D while writing that paper. My coauthor was a grad student having difficulty programming the simulations in R. I looked around and settled on D because the interoperability with R was so easy - we only wanted to rewrite the bottleneck, not the whole thing. D wasn't just fast, it made it easy to convert my thoughts into code. That was ten years ago.

Interesting! Thanks for sharing

Unfortunately there is no approved and mature instrument to use D for R package creation that will be accepted for CRAN

That's correct. I doubt there ever will be, though now that D is part of GCC, I suppose it's possible.

I don't know that this is a big constraint. You can add a Makefile to your package that compiles the D code into a shared library. If you install using devtools, it will build a shared library that is installed as part of the package. That is actually what I did for this paper - I wrote a package with D code and the grad student installed it/used it as a regular R package without knowing anything about D.

I created a Github repo with the simplest possible example to show how to do this.
