Calling C++ "void foo(Klass&)"

Hi all,
Currently, it is not possible to call the C++ function "void
foo(Klass&)" when Klass is an extern(C++) _class_ on the D side.
You have to declare Klass as a D _struct_, otherwise there is no
way to get the correct mangling. When Klass has virtual
functions, you're hosed.
For more context (involving "const"), see:

Is this problem on anybody's radar?
What are the ideas to resolve this issue, or are we content never
to solve it?
At the very least, we should add information about this to the
C++ interfacing page, https://dlang.org/spec/cpp_interface.html .
