No, they behave differently!
The modules are *not* superclasses of the classes they are mixed into:

  C1 = Class.new Object
  C2 = Class.new C1
  C3 = Class.new C2

  C3.superclass  # => C2
  C3.superclass.superclass  # => C1

  M1 = Module.new
  M2 = Module.new
  C4 = Class.new { include M2, M1 }

  C4.superclass  # => Object
