Modules and foo

I have some questions about some things that i don't understand..
here is some code fragments

I have two questions.

One.. is there a better way to inherit between modules
that i don't know about?

Two.. why, when a method is called in module Bar does the Module InstanceMethods in Bar not get included?

module Blah
      def self.append_features(base)
           super
           base.extend ClassMethods
      end
      module InstanceMethods
           def visible

           end
      end
      module ClassMethods

             def _do_other
    
    class_eval <<-EOV
      include InstanceMethods
    EOV

      end

             def do_blah
    "blah"
             end
      end
end

module Bar
      def self.append_features(base)
           super
           base.extend ClassMethod

···

#
# This is ugly
# How do i avoid this?
#
           base.extend Blah::ClassMethods
      end
      module InstanceMethods
           def hidden

           end
      end
      module ClassMethods
       def do_bar
      do_blah
       #
       # When i do this , i don't get the InstanceMethods of Bar, just Blah
       #
      _do_other
    end
      end

end

Do you mean "class InstanceMethods"? Modules are collections, often of classes.

I'm following a pattern that Rails uses for the "Acts As" code.

I don't want to muddle with the inheritance tree, i just want to mix-in methods.
