Inline your helper_method declaration

Remember, def is just a special function in ruby and as such it has a return value that is a symbol that is the name of the function being defined.

That allows us to do some cool (weird?) looking things with class methods that take a symbol that refers to a function, like the helper_method call in a controller.

  class DataController < BaseController
  #actions and whatever


  helper_method def format_that_data(data)
    "#{data[0]} X #{data[1]}"
