Yes you can but whatever you put() into the array is immediately 
popFront()'ed from the array. ;) You must use a temporary surrogate slice:

import std.stdio;
import std.range;

void main()
{
     int[] array = [ 1, 2, 3 ];
     int[] slice = array;

     put(slice, 100);  // <-- slice shrinks! :)
}

slice.length is 2 and array.length is 3.

Agreed.
