This is not necessarily true. You should be able to inherit from
an extern(C++) class just fine on the C++ side. Of course, Walter
is busy converting various internals to D, but it should be
possible to keep the parts you need accessible from C++.
Please make sure let us know if we can do anything on the LDC
side to make the transition easier.
