+You may be thinking it's quite cumbersome that arrays are fixed length and most of the time you probably wont be using them! Go has _slices_ which are dynamic in size and most of the time you will probably be using them instead.

+An interesting property of arrays though is the size is encoded in its type. If you try and pass an `[4]int` into a function that expects `[5]int`, it wont compile
