What do you think about Python's new Set Literal (2.7a3+)?
<p>What do you think about Python's new <a href="http://docs.python.org/dev/whatsnew/2.7.html#other-language-changes">Set Literal</a> (2.7a3+)?</p>

<pre><code>&gt;&gt;&gt; {1,1,2,3,3}
set([1, 2, 3])
</code></pre>

<p>Wouldn't it make some confusions with Array, If you came from different programming backgrounds like C/C++, C#, Java?</p>
