Test code:

----
import std.container;

void main()
{
  Array!int myList;
  myList.length = 2;

  auto range = myList[];
  myList[0] += 1;
  range[0] += 1; //Doesn't compile
}
----
..\..\src\phobos\std\container.d(1758): Error: expression this._outer of type
Array!(int) does not have a boolean value
..\..\src\phobos\std\container.d(1758): Error: undefined identifier '_payload'
..\..\src\phobos\std\container.d(1759): Error: undefined identifier '_payload'
main.d(10): Error: template instance
std.container.Array!(int).Array.Range.opIndexOpAssign!("+") error instantiating
----

Fault is here:

----phobos / std / container.d l.
        void opIndexOpAssign(string op)(T value, size_t i)
        {
            enforce(_outer && _a + i < _b && _b <= _outer._payload.length);
            mixin("_outer._payload.ptr[_a + i] "~op~"= value;");
        }
----
Suggest changing to:
----
        void opIndexOpAssign(string op)(T value, size_t i)
        {
            enforce(_a + i < _b && _b <= _outer._data._payload.length);
            mixin("_outer._data._payload.ptr[_a + i] "~op~"= value;");
        }
