Subject: How to add a instance variable through a mixin?

Hi,

I would like to have a mixin which adds an instance variable to a
class. I ve tried it the following way:

I ve defined a little module:
module MyApp
  module MyMixin
    def self.included(base)
      @should_be_an_instance_variable = nil
    end
 end
end

which is included by my little class:
class MyClass
  include MyApp::MyMixin
end

However, it seems that @should_be_an_instance_variable is currently
defined per mixin, but I would like to have a unique one for each
object of MyClass.

Maybe anybody can help me?
Thanks a lot in advance.
