Copy-paste is very handy when complaining about compile errors ;).
You might want to copy-paste the errors themselves too.

Yes I did. And I just did it again. Compiles just fine:

     D:\Temp>cat test.d
     class Board {
          Board outer;
          this() { outer = this; }
          class Cell {
              Cell dup() {
                  return outer.new Cell;
              }
          }
     }
     D:\Temp>dmd -c test.d

     D:\Temp>

That's DMD v0.161 though. v0.162 has an unrelated bug causing it to 
segfault when compiling some of my code :(.
