There's no reason why this issue can't be easily fixed. Because 
when you include narrow string or wchar, there is no problem of 
not being able to save(). Here is the proof:
```d
void main()
{
   ushort[] i = [1, 2, 3];
   auto r = R(i);
   auto arr = [r, r, r];

   import std.conv : text;
   auto str = arr.text;
   assert(!arr.empty);

   foreach(n; arr)
   {
     n.writefln!"%(%d, %)";
   } // no problem
}
```
