The pop() function is similar to the pop instruction in assembly and treats the array like a stack.

my @array;
$array[$#array] = 1;
$popped = pop(@array);

The same affect can be acheived with:

$popped = $array[$#array--];
RPU0j.png Executing pop() on an array will delete the highest order array element.
