I have to say, my first (and rather uncharitable) thought when I saw this was, &quot;Does the world really need another templating language?&quot;  I&#x27;ve been really happy with Haml for years now, and have reached moderate levels of satisfaction with Jade when I can&#x27;t use Haml.<p>Also, it wasn&#x27;t clear to me from looking at <a href="https:&#x2F;&#x2F;gitlab.com&#x2F;Polly-lang&#x2F;Polly&#x2F;blob&#x2F;master&#x2F;GUIDE.md#variables" rel="nofollow">https:&#x2F;&#x2F;gitlab.com&#x2F;Polly-lang&#x2F;Polly&#x2F;blob&#x2F;master&#x2F;GUIDE.md#var...</a> how I would actually write, say, an email addressing including an &quot;@&quot; symbol (I&#x27;m sure it&#x27;s possible, just not documented there).
