In this case you can interpret the nested arrays in this way.
But that's not a general rule for arrays.
You could also consider an array that contains several columns,
where each column has a couple of rows. That really depends on
how you want to look at your data.

Well, he explaines at the start of chapter 8 that each "slot" is
simply pointing to some object (which can be anything).
And there is nothing special about "how an array within an array works".

This is an array:

   objects = [5, ['a', 'b'], Time.new]

It's first element `objects[0]` is  5 and `objects[1]` is the
array ['a', 'b'].
