title: Python element-wise tuple operations like sum
body: <p>Is there anyway to get tuple operations in Python to work like this:</p>
  
  <pre><code>&gt;&gt;&gt; a = (1,2,3)
  &gt;&gt;&gt; b = (3,2,1)
  &gt;&gt;&gt; a + b
  (4,4,4)
  </code></pre>
  
  <p>instead of:</p>
  
  <pre><code>&gt;&gt;&gt; a = (1,2,3)
  &gt;&gt;&gt; b = (3,2,1)
  &gt;&gt;&gt; a + b
  (1,2,3,3,2,1)
  </code></pre>
  
  <p>I know it works like that because the <code>__add__</code> and <code>__mul__</code> methods are defined to work like that. So the only way would be to redefine them?</p>
