Status of chained assignment in Python
<p>At several occasions I stumbled upon C-style assignment in Python such as <code>a = b = 0</code>. By diligent Googling I found out that this is called chained assignment: [<a href="http://en.wikipedia.org/wiki/Assignment_%28computer_science%29#Chained_assignment" rel="nofollow">1</a>],[<a href="http://stackoverflow.com/questions/11498441/what-is-this-kind-of-assignment-in-python-called-a-b-true">2</a>],[<a href="http://stackoverflow.com/questions/7601823/how-do-chained-assignments-work">3</a>]. However, it appears that this feature is not mentioned in the <a href="http://docs.python.org/3/reference/simple_stmts.html#assignment-statements" rel="nofollow">official documentation</a>.</p>

<p>Does this mean that chained assignment is still in experimental phase, or simply that the official documentation is slightly behind the development?</p>
