Thank you, this is _exactly_ what I was looking for!

Or import std.array to get the range primitives for slices:
import std.array;
void main()
{
auto arr = [1, 2, 3, 4];
arr.popFront();
assert(arr.front == 2);
}

Given an assosiative array : int[string] k, is there a way
(either phobos or tango) to pop the first element of this array
and append it to another array?
I can come up with a primitive soluiton:
int[string] k;
// populate k here
int[string] j;
foreach(sttring key, int val; k)
{
j[key] =
Aso, I wanted to mention that I did not find much info in the
manual page on this.

This is OK, and you can encapsulate this into a little function.
But you are not removing the pair from the first associative
array. So you have to remove the item before
