We need to support different C++ name mangling schemes.

Right, that's fairly straightforward to implement, we could 
probably use a UDA to change it (@VisualCpp void foo()) or choose 
the most sane default with version(Windows), version(GDC), etc.

Also the next step would be:
mixin(importCPP("myheader.h"));


You know I was actually thinking about that. Either using a dummy 
D class and going over it to build the C++ object:

class Test_Cpp {
   int num;
   int num2;
   void talk();
   final void sayHi(); // or whatever i dont have the file open 
right now
}

alias AccessCpp!Test_Cpp Test; // AccessCPP parses it into the 
equivalent c++ definitions then builds out the structs and mangle 
schemes


Or reading the .h file like you said. Which would be pretty hard, 
even to do just partially, since the C++ definition might have 
inline definitions, #includes, macros and so on that just totally 
confuse the parser.
