Configure flag for turning on/off the function alias "_()" for "gettext()"

Hello!

Not sure if this is right place for this, but anyways:

Wouldn't it be nice to have a configure flag for turning on/off the 
function alias _() for the gettext() function, or maybe even a php.ini 
setting if that's possible.

If this feature existed it would be possible to create your own _() 
function which could do things in addition to calling gettext().

Example:
function _($string) {
	$ret = gettext($string);
	if ($ret == $string) {
		/***
		... notify of missing msgid in .mo/.po file ...
		***/
	}
	return $ret;
}

This however would be slower than using the alias _() directly, but it 
would be _VERY_ nice to have for debugging and development purposes.
