I guess I understand this, and I'm willing to live with it
because I personally don't ever want to nest arrays inside
each other. Too weird for me.

So I would be happy if we could come up with an array
method that makes a between-shallow-and-deep copy. We don't
have to name it clone, since that has many meanings. How
about:

class Array
  def copy
    return []+self
  end
end
