Subject: Adding a method to a single object

Hi,

how is it possible to add a method to a single object programatically?
E.g. I want to write a method

class Object

   def rename_method(old_id, new_id)
     ...
   end

end

The method shall rename a method for a specific instance of any class, 
e.g. the following should be possible:


a = 5
5.rename_method :times, :veces

5.times { ... }
   -> Error, Method "times"does not exist

5.veces { ... }
   -> Expected behaviour

I already succeeded in renaming methods for whole classes, but for a 
single instance?

I do not really have a use case for such a method, but it is fun 
learning about the object model in Ruby.

Best regards,
    Marco
