Description:
------------
i have defined a method in 'myClass' named 'myMethod' and it can be called statically.

i cant use call_user_func() because i need to pass a variable by reference and since call_user_func() is a function itself i cant get the variable passed (if i add the "&" to the variable in call_user_func i get a "calltime-pass-by-reference" error in php5, but it works for now)

tried with 4.3.8 and 5.0.3RC1

Reproduce code:
---------------
Generates Error:
<?
$meth = 'myMethod';
is_callable(array('myClass',$meth),null,$callname);
echo $callname($variable);
?>

Works:
<?
echo myClass::myMethod($variable);
?>

Expected result:
----------------
myClass::myMethod() should be called


Actual result:
--------------
PHP Fatal error: Call to undefined function myClass::myMethod() in XXX on line XXX
