class MetaDerp
  ### DENSE HORRIBLE CODE
  # This should be broken up into smaller chunks possibly moved out into a mixin
  # to hide it's horribleness
  class << self
    def hunt(name, *keys)
      class_eval %[
        def #{name}
          #{keys.map{|key| "row[#{key.inspect}]" }.join(' || ')}
        end
      ]
    end
  end

  ### Pretty Expressive Beatiful Code
  attr_accessor :row

  hunt :message, :message, :are_you_there?, :hello
end


m = MetaDerp.new
m.row = { :hello => 'Metaprogramming' }
puts m.message
m.row = { :are_you_there? => 'Yup', :hello => 'Metaprogramming' }
puts m.message
m.row = { :message => 'It works!' }
puts m.message
m.row = { :"no one will look here" => 'And why should they?' }
puts m.message
