What about (just tries)

    class User

      def initialize(name)
        @name = name
      end

      def say_hello
        puts "hello #{@name}"
      end

      def say_hi(friend)
        puts "hi #{@name} from #{friend}"
      end

      def say_bye(a, b = 'Anna')
        puts "bye #{a} and #{b}"
      end

    end

    User.class_eval do
      User.instance_methods(false).each do |method|
        original = instance_method(method)
        define_method method do |*options| 
          parameters = original.parameters
          if parameters.empty?
            original.bind(self).call
          else
            original.bind(self).call(*options)
          end
          puts __method__
        end
      end
    end

    user = User.new("John")

    user.say_hello
    user.say_hi("Bob")
    user.say_bye("Bob")
    user.say_bye("Bob", "Lisa")

outputs:

    hello John
    say_hello
    hi John from Bob
    say_hi
    bye Bob and Anna
    say_bye
    bye Bob and Lisa
    say_bye
