Subject: extend weirdness?

Hi Group,

This code:
    module Foo
      def self.included(base)
        base.class_eval <<-end_eval
          def self.meth
            "Foo"
          end
        end_eval
      end
    end

    module Bar
      def self.included(base)
        base.class_eval do
          extend ClassMethods
        end
      end

      module ClassMethods
        def meth
          "Bar"
        end
      end
    end

    class A
      include Foo
      include Bar
    end

    puts A.meth

produces:
    Foo

whereas I would expect it to produce "Bar"

Can anyone explain what's going on here?  i.e. Why the latter extend
with Bar doesn't over-write the class method introduced by Foo

Cheers,
Ian White
