Language Class - loading multiple language files

[eluser]GSV Sleeper Service[/eluser]
the docs in system/libraries/Language.php states

Code:

/**
* Load a language file
*
* @access    public
* @param    mixed    the name of the language file to be loaded. Can be an array
* @param    string    the language (english, etc.)
* @return    void
*/

that 'Can be an array' bit is a lie, you can't pass an array or you'll get an error along the lines of 'Unable to load the requested language file: language/Array_lang.php

Is this a planned feature? or is it a relic from an old version?

i think it's a relic. the whole method is based on a string filename. It seems the EL developers are not big on updating code comments as someone else found several wrongly commented @return values.
