Subject: change namespace scope / nesting problem

Hello everybody. I am having problem with nested modules and includes
not changing namespaces.
I am trying to be DRY by moving out some common methods into a module,
but when I do that, my nesting changes and the class names are not
resolved properly.

For example if I have modules Foo and Foo2, and each of those modules
have 2 classes Bar and Helper. I also have Module Mixin:A which has
methods for class Bar for each module. If a method in Mixin::A tries to
access Helper, I get error Mixin::A::Helper is undefined. It is
resolving to Mixin::A namespace instead of Foo or Foo2. Here is the
sample code that demonstrates my problem.

Thanks.

module Mixins; end

module Mixins::A
  def self.included(base)
    base.class_eval do
      def test_it
        Helper
      end
    end
  end
end

module Foo
  class Helper
  end

  class Bar
    include Mixins::A
  end
end

module Foo2
  class Helper
  end

  class Bar
    include Mixins::A
  end
end

Foo::Bar.new.test_it    #=> should return Foo::Helper
Foo2::Bar.new.test_it    #=> Should return Foo2::Helper
