Arrays are values and cannot be resized after creation.
var array [10]int;
Arrays can be sliced like in D:
var slice []int = array[5:7];
The length of this slice is len(slice) == 7 - 5 == 2. The *capacity*
of this slice is cap(slice) == 10 - 5 == 5.
You can slice a slice beyond its length, up to capacity:
var slice2 []int = slice[4:5];
Effectively slice is a tail of an array, with optional subdivision into
sub-head and sub-tail.
There is no array nor slice concatenation, nor any other way to change
slice length except slicing.
