[Typo3-dev] User extension of class.t3lib_div.php

[=?us-ascii?Q?=22Kasper_Sk=E5rh=F8j=22?=]

It would be quite easy to make a search/replace on t3lib_div:: to $GLOBALS['DIV']->

(and for other classes as well) but what is the performance loss ? ( if any) - and it is also uglier.

But it would be backwards compatible!


We can discuss later this month.



God bless
