dastardly code that I'm simultaneously proud of and scarred by

gistfile1.rb

      @translations_split = {}
      @translations.each do |key, default_translation|
        tran_parts = key.split('.')
        current_position = @translations_split
        while tran_parts.length > 1
          next_part = tran_parts.shift
          unless current_position[next_part]
            current_position[next_part] = {}
          end
          current_position = current_position[next_part]
        end
        current_position[tran_parts.first] = default_translation
      end
