 I ran into this issue while working on a site where WordPress handles the
 front-end and CakePHP runs in the background to handle some js application
 outputs.

 CakePHP also defines a
 {{{
 __()
 }}}
 translation function in its global scope, removing the
 {{{
 if(!function_exists('__'))
 }}}
 check on the translation function in wp-includes/l10n.php causes a fatal
 redeclaration error when both system cores are loaded on a request.

 Was there a reason this check was removed?
