How to iterate over case insensitive sorted dictionary items?
<p>Example:</p>

<pre><code>&gt;&gt;&gt; d = {'answer':1, 'Question':2}  
&gt;&gt;&gt; for i, j in sorted(d.items()): print i
Question
answer
</code></pre>

<p>I would like case insensitive list:</p>

<pre><code>answer
Question
</code></pre>

<p>and I believe it can be done in simple Pytonic way</p>
