Given a C++ class that looks like this:

class Foo {
    static void Initialize(const SomeObject&);

}

The documentation at [1] doesn't say anything about how to handle 
static member functions like Initialize, nor do I see anything 
about references. I assume I can declare any reference function 
parameters using D's ref, but I have no idea how to declare 
static methods. My questions:

1) Am I right about ref?

2) Do I need to create a wrapper function in C or C++ for static 
member functions?

I would assume so. It's just a pointer under the hood.

 functions?

The documentation for the C++ support is very outdated. I recommend to 
give it a try and see what happens :). Alternatively look in the DMD 
test suite and see what you can find, or the DMD source code now when 
it's in D.

In D classes are reference types by default.

Yes, I get that. But how does that work when you're linking to a 
C++ library and the translation of the C++ class to D is an 
interface? Or is it possible now to link D classes directly with 
C classes?

Yes, of course. I just want to verify that the D ref and C++ ref 
are equivalent.

I realize I can do it myself when I sit down this weekend and 
start exploring it, but I'm hoping someone can point me to a blog 
post, some sample code, or just give me some insights to save 
time.

Classes and templates except for special members (which are 
usually relied upon heavily in C++ code, but maybe your C++ code 
is unusual).

You can see bugzilla issues marked with C++ keyword. The docs 
were deemed unworthy because of skills required to write C++ 
bindings. Maybe because it's still not practical as it doesn't 
support critical C++ idioms like RAII.
