title: Calling the setter of a super class in a mixin
body: <p>Suppose I have the following (not quite biologically correct) classes:</p>
  
  <pre><code>class AnimalBaseClass:
      def __init__(self):
          self._limbs = None
  
      @property
      def limbs(self):
          return self._limbs
  
      @limbs.setter
      def limbs(self, value):
          self.paws = value
          self._limbs = value
  
  
  class BipedalMixIn:
      @property
      def limbs(self):
          return super().limbs
  
      @limbs.setter
      def limbs(self, value):
          self.bipedal = (value == 2)
          # does not work
          super().limbs = value
  </code></pre>
  
  <p>Here <code>super().limbs = value</code> is <a href="http://bugs.python.org/issue14965" rel="nofollow">not supported by python</a>. If <code>BipedalMixIn</code> was not a mixin, I could use the super class's name directly, but is there any simple alternative, to call the super class's setter in a mixin?</p>
