Being able to use more D would be nice! But the binding issues remain the same there. There recently was talk about having the D compiler emit C++ headers for exports from D modules automatically. This would be an instant killer feature for me.
Yes, dpp has issues with C++ constructs according to its readme unless that changed recently. I am talking about the inverse: have dmd generate a C++ header automatically for extern(C++) declarations during compilation. This was discussed quite recently.
