While not exactly the same, this can be worked around by using 
the constructor of the base class.

```d
class Base {
     private string _stringof;
     this(this This)() { _stringof = This.stringof; }

     string serialize() {
         return _stringof;
     }
  }

  class Derived : Base {

  }

  void main() {
     Base b = new Derived();
     assert(b.serialize() == "Derived"); // Passes
  }
```
