Yes, class *refs* are always pointers. *scope* classes are
deprecated (I don't think I've ever seen one); with `scope c =
new Object`, you can have the compiler allocate a class
*instance* on the stack for you, but `c` is still a *ref*.
`emplace` doesn't allocate, you have to pass the memory
explicitly. A class *instance* can also live in the static data
segment (`static immutable myStaticObject = new Object;`);
`extern(C++)` class instances can also live on the C++ heap/stack
etc. etc.
