Wow!  I have a fundamental misunderstanding of mixins apparently. I
see that you are correct. c doesn't respond to croak in the following
code. However, I don't understand why. Doesn't the include add
instance methods from the module M to the class C?

module M
  def self.croak
    puts 'croak'
  end
end

class C
  include M
end

c = C.new
c.croak
