Thank you, Sebastian!  I lost track of that.

OK, here we go, then:

class Array
  def depthen
    base_depth = first
    result = []

    each do |depth|
      array_end = result
      (depth - base_depth).times do
        array_end << [] unless array_end.last.kind_of? Array
        array_end = array_end.last
      end
      array_end << depth
    end

    result
  end
end
