And I know that. :) We don't know who else is reading these threads, so 
I didn't want to give wrong impression.

Copying would happen if we added slicing on the left-hand side. However, 
I realized that the following fails with a RangeError:

void main() {
   auto arr = [1, 2, 3];
   arr[0..$-1] = arr[1..$];    // <-- Runtime error
}

I suspect the length of the array is stamped too soon. (?)

Should that operation be supported?
