In which "real-use" cases item.__dict__.iteritems() is used?
<p>Yesterday i was reading some questions here on SO and i came to know <code>item.__dict__.iteritems()</code>.
I must admit that i do not know how, when  or why use that, and i also admit it looks beautiful, pythonic.</p>

<p>So, what are some "real-world" uses of that?</p>
