Ok, if you can resolve everything this way.

I agree that you end up spending way too much effort on bringing 
C++ into D, for it to be meaningful. My headerfiles used to be 
like 10-20% of my C++ source. Now it is at 40-50% of my C++ 
source... My C++ library code is at 90% header file only. Things 
like concepts will probably just ensure that this trend persists.

So I am not sure if interfacing with compiled C++ only is 
particularly useful. I think you need support for generating C++ 
source code stubs for interfacing so that you can use inlined 
non-instantiated C++ code (or just stick to C).

LLVM whole program optimization (linking LLVM IR) would "melt" it 
all together reasonably efficiently.
