except when you use that format you can't pass references to  
functions, as it makes copies of everything

chx wrote a simple call_user_func array replacement that passes  
references a few years ago.

basically :

function call($func, &$var1, &$var2, &$var3, &$var4, &$var5, & 
$var6 ... etc) {
	if (function_exists($func) {
         	return $func($func, &$var1, &$var2, &$var3, &$var4, &$var5, & 
$var6 ... etc);
	}
}
