I think that has to do a lot with your "school".
Have a try with it, i'm sure you'll love it after while :P

Let me only add if you want performance in this case you could just do:
@process_args ||= lambda do |node, has_block|
    ... # i don't want to access to the outer node
        # and "node" says more than "n"
  end

this is a very simple cache system ;)
