Any word on the return-type const syntax?

No, sorry - I figured out the problem. Invariant classes and invariant
member functions make no sense. This was discussed in another thread
somewhere, and Walter agreed. So in fact, you only have to consider
the const and non-const instantiations. You can forget the invariant
one. So, in fact, you only need

     class MyArray(T)
     {
         T[] a;

         T* ptr() { return a.ptr; }
         const(T)* ptr() const { return a.ptr; }
     }
