First attempt at a simplified middleground record for exporting.

flat_person.rb

class FlatPerson
  
  def initialize(person)
    raise TypeMismatch unless person.class == Person
    
    person.attribute_names.each do |attr|
      eval("@#{attr} = person.#{attr}")
    end
    
  end
  
  def method_missing(arg)
    if eval("@#{arg}")
      eval("@#{arg}")
    end
  end
end

class TypeMismatch < StandardError; end
