Replace Dynamic Receptor with Dynamic Method Definition

You have methods you want to handle dynamically without the pain of debug- gingmethod_missing.

Use dynamic method definition to define the necessary methods.

class Decorator
  def initialize(subject)
    @subject = subject
  end

  def method_missing(sym, *args, &block)
    @subject.send sym, *args, &block
  end
end 

class Decorator
  def initialize(subject)
    subject.public_methods(false).each do |meth|
      (class << self; self; end).class_eval do
        define_method meth do |*args|
          subject.send meth, *args
        end
      end
    end
  end
end
