Well, here's some cool code then:

   >> module M; def hi; "hi"; end; end
   => nil
   
   >> class A; end
   => nil
   
   >> A.include M
   NameError: private method `include' called for A:Class
           from (irb):3

   >> class Module
   >>   def inc(*args)
   >>     include *args
   >>   end
   >> end
   => nil
   
   >> A.inc M
   => A
   
   >> A.new.hi
   => "hi"
