This works on my confuser (DMD 2.013, DMD 1.029):

   string[] a = ["Hello", "World"];
   string[][] b;

   b ~= a.dup;

   a[0] = "HAI";
   a[1] = "WURLD!1";

   b ~= a.dup;

   writefln(b); // prints [[Hello,World],[HAI,WORLD!!!1]]


Without the .dups, output is [[HAI,WORLD!!!1],[HAI,WORLD!!!1]].
