The fact that foreach with a ref item or foreach with an index 
doesn't work makes using them a lot more of a hassle than 
built-in arrays though.

     void main()
     {
         import std.container, std.stdio;
         Array!int a = make!(Array!int)(1,2,3,4);
         foreach(ref v; a)
         {
             v *= v; // no effect on a
         }

         writeln(a[]); // [1, 2, 3, 4]

         foreach(v, i; a) // Error: cannot infer argument types
         {
             a[i] *= v;
         }
     }
