Description:
------------
The function is_callable() says, that abstract static method _IS_ callable. But it is abstract, it has no body.

    abstract class Foo {
        abstract static function bar();
    }
    # PHP Strict Standards: Static function Foo::bar() should not be abstract
    # is Foo::bar() callable?
    var_dump( is_callable(array("Foo", "bar")) );
    # bool(true)
    # O_o Ok, let's try...
    Foo::bar();
    # Fatal error: Cannot call abstract method Foo::bar()

Yes, I see a Strict. Anyway, is_callable() lies. I have checked this in 5.3.10, 5.3.6 and 5.2.17.

Test script:
---------------
abstract class Foo {
    abstract static function bar();
}

var_dump( is_callable(array("Foo", "bar")) );
Foo::bar();


Expected result:
----------------
bool(false)
Fatal error

Actual result:
--------------
bool(true)
Fatal error
