Describe your suggestion

I am not sure that the example is doing a good use of the term immutable. They example:

immutable = Array.new(3) { Array.new(2) }

Creates and array which we clearly can change:

irb(main):011> immutable[0][0] = 1000
=> 1000
irb(main):012> immutable << "new element"
=> [[1000, nil], [nil, nil], [nil, nil], "new element"]

It might not bother new students of programming, but it does look strange if you already are
coming from a different language ...

I believe that a more accurate description can be used here. For example:

An array with references to different objects
