Subject: Re: Should every method have a module method?

Could one use subclasses in a manner of temporary delegation?

| class String
|    def inflect
|      return Inflection.new(self)
|    end
|
|    class Inflection < self
|      def initialize( delegate )
|        super( delegate )
|        @delegate = delegate
|      end
|      def plural
|        result = word.to_s.dup
|        plural_rules.each do |(rule, replacement)|
|          break if result.gsub!(rule, replacement)
|        end
|        return result
|      end
|    end
|
|  end

Then

| s = "dog"
| s.inflect.class  #=> Inflection
| s.inflect.plural  #=> "dogs"
| s.inflect.plural.class  #=> String
