Subject: append_features(mod) -- mod.kind_of? makes absolutely no sense

First of all, if class Class inherits class Module then why isn't 
append_features defined for Class?

  class Whatever
    append_features MyModule
  end
  # => undefined method `append_features' for Whatever:Class (NoMethodError)

But even more nonsensical:

  class Module
    alias append_features_orig append_features
    def append_features(mod)
      p mod, mod.class
      append_features_orig(mod)
    end
  end
  module MyModule
    def wow
      puts "You have to be kidding!"
    end
  end
  class Test
    include MyModule
  end
  t = Test.new
  t.wow

Produces:

  Test
  Class
  You have to be kidding!

Its my understanding the include passes each Module to append_features, but 
that's not what append_features is saying. In fact, according to this 
append_features is appending Test to Test, even though it works fine. Please, 
tell me I'm over looking the obvious here.
