I am running hybrid D/C++ apps. I found it to work best when you 
give D the control over the main method, e.g. the program entry 
point should be in D land. Then simply call a C++ function from 
there to initialize your c++ stuff.

I'm currently even running hybrid C++/D apps with dlls. E.g. 
multiple D dlls + multiple C++ dlls loaded by a c++ main program. 
But to do that I have heavy compiler + runtime modifications 
which are not ready yet to do a PR for them.
