According to that C++ / D .object files can interoperate both 
ways, but one has to be compiled before the other, order 
depending on direction.

My question is, can you have a class C (C++) use a class D 
(Dlang) in such a way that D can also use C as in the article?

I'm guessing using all pointers on the C++ side might work.  I 
have never gotten rid of cyclical dependencies in C++ other than 
putting a bunch of classes in the same file, but in D, cyclic 
dependency is resolved beautifully somehow, so I can split up my 
classes into each their own d-module.

At DConf, Manu indicated that that page is outdated and that D's C++ 
support is actually a lot better. He kind-of-promised to update that 
page but I doubt it happened yet if ever. :)

I don't think that's correct. The page is unfortunately unclear:

   "the first with a C++ compiler, the second with a D compiler"

could have better been written as

   "the C++ source file with a C++ compiler, and the D source file with 
a D compiler"

So what is the answer here?  I'm not sure what they were getting
