When append a key to an array in "if condition", an error of level E_NOTICE is generated.

[bryceliu]

Example:

// test.php
require '../libs/Smarty.class.php';
$smarty = new Smarty;
$smarty->debugging = true;
$smarty->caching = true;
$smarty->cache_lifetime = 120;
$smarty->assign('arr', ['first' => 10]);
$smarty->display('test.tpl');

// the template file: test.tpl
{if $arr.second = $arr.first + 100 nocache}
{$arr.first} - {$arr.second}
{/if}

Error as follows:

PHP Notice:  Undefined index: first in /home/bryce/git/smarty/demo/cache/77fd09ff9079054983b57cce4b84650d9500fb25.test.tpl.php on line 32

Maybe this is not allowed originally.>_<

This notice should have popped up just once when the modified template got recompiled.

The patch is now in dev-master. It will be included in 3.1.24 which will be released very soon.
