According to the docs: zip "offers mutation and swapping if all ranges offer it". But I still get an arrayful of nan's even if I do: auto arr3 = new double[10]; auto index = iota(10).array(); foreach(i, ref x; zip(index, arr3)) { x = i; } writeln(arr3); ... even though the array index ought to be mutable here. Tweaking to foreach(ref i, ref x; zip(index, arr3)) { x = i; } ... doesn't work either.
