In that case it's probable that you have another level of indirection,
and not have each child node directly as an instance variable. More
likely something like:

class Node
   attr_reader :children

  def initialize
    @children = []
  end

  def add_children node
    @children << children
  end

  def remove_leaves
    @children.delete_if {|node| node.leaf?}
  end
end

Missing some pieces, but you get the idea...
