I've done an initial release of the second version:

The two biggest changes are

- Moving to Dub as the default for compilation, which allows the 
use of any other Dub libraries
- It writes the wrappers for you. You write a D function and it 
converts it to R.

The part I haven't finished is in the other direction. For 
instance, suppose you have a D function that sends data to R many 
times. If you don't release the memory on the R side, your 
program's going to crash quickly. I haven't worked on this 
recently because I've mostly been calling D functions from R.
