HTML is/as a programming language
Reminds me of Genshi, which was really cool about.... 15 years ago. <a href="https:&#x2F;&#x2F;pythonhosted.org&#x2F;Genshi&#x2F;templates.html" rel="nofollow">https:&#x2F;&#x2F;pythonhosted.org&#x2F;Genshi&#x2F;templates.html</a><p>The big difference between Genshi and Jinja (which ended up winning) is that Genshi templates are valid XHTML using the &quot;py:&quot; XML namespace for control flow,  and Jinja templates use their own syntax (and therefore can template things other than XML).
