I suggest a simpler way - declare the C++ side of the D
interface in a way that matches the way D mangles it. It's
always been true that in order to interface D with C++ you'll
need to be a bit flexible on the C++ side.
Unfortunately, it's almost always the other way around - D code
trying to interop with one of the gazillions existing C++ libs,
and nobody wants to maintain his own fork with D-compatible glue
interfaces. How often did you use `const T *const` vs. `const T
*` in your C++ headers? ;) I think this would be a tiny change
for D, breaking almost no code and well worth the reduction in
required 'flexibility on the C++ side'.
