Lang files

I was looking at the lang demo and I was wondering if it is possible to use a lang file where it was in an array like


$Lang['c_text1'] = "Text1";
$Lang['c_text2'] = "Text2";
$Lang['c_text3'] = "Text3";
$Lang['c_backindex'] = "Back to index";

Or what if the lang is like so

$Lang['text1'] = "Text1";
$Lang['text2'] = "Text2";
$Lang['text3'] = "Text3";
$Lang['backindex'] = "Back to index";

Then what would be the best approach for using lang files with fast template?

//thi scan be a possible hack
$Lang['text1'] = "Text1";
$Lang['text2'] = "Text2";
$Lang['text3'] = "Text3";
$Lang['backindex'] = "Back to index";

// just extract your lang table into variables with lang_vars prefix
extract($Lang, EXTR_PREFIX_ALL, "lang_vars");

//.........
// after this you can use ft
$ft->multiple_assign("lang_vars");
