Is there something like

    extern "C" { void foo(); }

For D? That way you'd be able to use the LuaJIT ffi. That, in combination with what's in the OP, would be killer.

Yes [0].

    extern (C++) int foo(int i, int j, int k);

In fact, D can both access C++, and C++ can access D, as you can see further down that link, on classes.

But, if you don't want C++, then [1]:

    extern (C) int foo(int i, int j, int k);

Which is actually in the article.

Yep, except you'd write it

    extern(C) { void foo(); }

Here is an example:
