 Well, I've not understood what you want to do but I'll write something
 like this 


J>    def each( block = nil, &syntax_block )
J>      block ||= syntax_block
J>      block.call( self, @children.length())
J>      @children.each do |x|
J>        x.each block
J>      end
J>    end

   def each
      yield  self, @children.size
      @children.each do |x|
	 x.each do |y|
	    yield y
	 end
      end
   end
