As a polyglot, sometimes the existence of a certain library or interface greatly influences what language I decide to write something in.<p>Twig is indeed time-tested, but I don't see a good reason to use Twig unless you are already using Perl. I was kinda hoping this would give reasons to use Twig over proven XML libraries from other languages, but I suppose it makes sense given this article was published to a Perl specific website.<p>Nice write-up, though!
