Subject: [PATCH] Adding an if condition on a for tag is deprecated in Twig
 2.10.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I've got an error, running example from the docs. Here is the explanation: https://twig.symfony.com/doc/2.x/deprecated.html#tags
I propose to use a filter filter or an “if” condition inside the “for” body instead in this docs.
