You can almost always replace anything that "needs" to go in a .cpp
file with a single template specialization.

     template <class Ignored = void>
     struct whatever_
     {
        // ...
        static some_type thing;
     }
 
     typedef whatever_<> whatever;

Now use whatever:: to access everything.

Seems like it could work in this case.
