Consider, I have the following code:

auto a = [3, 6, 2, 1, 5, 4, 0];
auto indicies = iota(3);
auto ai = indexed(a, indicies);
//ai = indexed(ai, iota(2));
writeln(ai);

I confuse about comment line that I mark...

Not sure I'll be more helpful, but I'll try to add more details.
I have an array and I use `indexed` on it. Conceptually, I now
have a second array, but it doesn't exist in memory explicitly -
only a function to map indicies from "second array" to "first
array" is stored; all the values are stored once - in the "first
array".
Now, I want to have third array that will do the same trick with
the second array. The problem is that the second array is not
really an array (but, conceptually, it is an array with random
access). If I create a new variable with `auto` as type -
obviously, it works. But can I use the same variable I used to
store the "second array"? (In the provided code that doesn't work
because of the type mismatch).
