Thanks but I have one question.

.selectFromTuple!(0, 1).expand

Does this result in a copy? I avoided doing it like this because 
I was worried that I would copy every array. But I also don't 
fully understand when D will copy.


Also doing

  foreach(e;range){
    e[0] = 10;
    e[1] = 10.0f;
    writeln("element: ",e);
  }
  foreach(e;range){
    writeln("element: ",e);
  }

doesn't mutate the range at all.
