Latte variable increment ends with Parse Error, Nette 2.2.2

Hi, I have found issue when I have tried increment variable in latte template.
If a do this in template

<?php
{var $i = 0}
{var $i++}
?>

It will ends with Parse Error: syntax error, unexpected ‘=’

Incrementing like this in Nette > 2.1 worsk fine.

Here is template file

And here is Tracy output
