The non intialisation of variable

Hi,

It's my first mail to the Smarty devel Mailing list. I use smarty for my 
project and I read the code. But I notice that a lot of variable aren't 
initialized, but in PHP 5 a recommandation is the initialisation of variables. 
an php error STRICT appear. So can I have send diff with this initializations ?
