Concerning the magical constant __CLASS__

<?php
class foo
{
    function a()
    {
        print __CLASS__ . "\n";
    }
}

class bar extends foo
{
    function b()
    {
        print __CLASS__ . "\n";
    }
}

$foo = new foo;
$bar = new bar;
print '<pre>';
$foo->a();              // foo
$bar->a();              // foo
$bar->b();              // bar
print '</pre>';
?>

I'm not sure about the definition of magical constant,
but IMHO __CLASS__ should be changed to reflect
the current class that it is in at that moment.
This would be useful when use it in a static method
where get_class() cannot be used.
