Description:
------------
ReflectionMethod or ReflectionFunction reflects a funtion with arguments shoule be passed by reference, when invokeArgs cause invocation failed with a Exception.

I think this should been noted in php manual

Test script:
---------------
function who(&$name) {
    echo $name;
}
$name = "laruence";
$method = new ReflectionFunction("who");
$method->invokeArgs(array($name));


Expected result:
----------------
"laruence"

Actual result:
--------------
Uncaught exception 'ReflectionException' with message
 'Invocation of function who() failed'
