[PHP-DEV] Bug #61033 __FUNCTION__ doesn't report correctly in alias trait methods

Hello everyone,

I've recently came across an odd situation where __FUNCTION__ can 
produce a misleading results when using traits with aliased methods, see 
https://bugs.php.net/bug.php?id=61033. 
<https://bugs.php.net/bug.php?id=61033>
This has been closed and I've been asked start a discussion on here if I 
disagree with the ruling. The reason why I feel this should be changes 
to reflect the actual called function name is that one of main uses of 
the __FUNCTION__ constant it to refer back to the function that is 
currently running, for the use recursive functions:

trait FooTrait {
     public function foo($n) {
         if ($n == 0) return;
         echo $n . PHP_EOL;
         $function = __FUNCTION__;
         $this->$function(--$n);
     }
}

class MyClass {
     use FooTrait { foo as public countdown; }
     public function foo() {
         echo 'MyClass::foo()';
     }
}

$instance = new MyClass();
$instance->countdown(3);

This example will produce running (PHP 5.4 RC7):

     10
     MyClass::foo()

Which as you can see is not the desired effect.

I send this email in the hope this can get the discussion under way 
regarding the magic constant __FUNCTION__.

Thanks,
