Hi,
Are there any recent improvements in how D interfaces with C++? I 
got the impression that some work has been done on that, in order 
to make DMD a self-hosting compiler.

I do not know of any recent improvements.

The current plan to make DMD self-hosting seems to be a 
conversion tool. The transition would one step then. The 
challenge is mostly on LDC then to use the C++ LLVM bindings.

I'm aware of the conversion tool, but it seems it will only apply 
to the frontend? The DMD backend will be left as is.

The DM backend has some legal issues. Symantec owns part of it 
and does not relicence it. Converting it to D would not change 
that, since the D version is still derived work.

Writing a whole new backend in D is not feasible. There are so 
many more important tasks. However, in the Open Source world, 
nobody can stop you from doing it. ;)
