Had a small typo, here's the fixed example:

def generate &name
  eval("self",name.binding).class.class_eval <<-EOS
    class #{name.call}
      def to_s
        "#{name.call}"
      end
    end
  EOS
end

class Universe
  def initialize
    generate{:Planet}
  end
end

generate{:Thing}

Universe.new

puts Universe::Planet.new
puts Thing.new
