I don't understand your question yet, but perhaps the following will
help. If this is not what you meant, please post exactly the code you
would like to write, and what results you would like from that code.



  module AutoMethodMaker
    def self.included(base)
      base.extend(ClassMethods)
    end
    def method_missing(method_name,*args)
      if self.class.maybe_make_method(method_name,*args)
        self.send(method_name,*args)
      end
    end
    module ClassMethods
      def methods_made
        @methods_made ||= []
      end

      def auto_make_methods(pattern,&block)
        (@auto_make_methods ||= {})[ pattern ] = block
      end

      def maybe_make_method(method_name,*args)
        @auto_make_methods.each do |pattern,block|
          if pattern===method_name
            define_method(method_name,&block)
            methods_made << method_name
            return true
          end
        end
      end

    end
  end

  class Flower
    include AutoMethodMaker
    auto_make_methods /special_.+/ do
      puts "Special flower #{__method__[/special_(.+)/,1]}!!"
    end
    auto_make_methods /.+/ do
      puts "I am a #{__method__}"
    end
    def standard
      puts "I am a built-in method."
    end
  end

  f = Flower.new
  p Flower.methods_made #=> []
  f.jasmine             #=> I am a jasmine
  f.rose                #=> I am a rose
  f.rose                #=> I am a rose
  f.special_rose        #=> Special flower rose!!
  f.standard            #=> I am a built-in method.
  f.lotus               #=> I am a lotus
  p Flower.methods_made #=> [:jasmine, :rose, :special_rose, :lotus]
