Help to identify python module (preprocessor?) "python -m dg"
<p>On the background of this image <img src="http://i.stack.imgur.com/PgPcR.jpg" alt="image"> you can find some code, that looks like written in extended python dialect, which have to be processed with “python -m dg” to get “normal” python code.
Google has no results for “python -m dg” query, and yandex.ru has only one page in cache, which briefly mention one example</p>

<pre><code>python  -m dg  &lt;&lt;&lt; 'sum $ map int $ str 2 ** 1000'
</code></pre>

<p>which seems to be equivalent of</p>

<pre><code>sum(map(int, str(2**1000)))
</code></pre>

<p>Do you know what this is all about? I want to take a look at this tool, but can't find any links…</p>
