Description:
------------
When trying to call a function stored in a static property I get the "Undefined 
variable" notice and a "Function must be a string" fatal error. This happens 
whether or not the function is stored directly in the property or in an array.

A work around (for now) seems to be storing the property into a temp variable.

Test script:
---------------
// Test Case 1:

class Foo
{
	public static $bar;
}

Foo::$bar = function() {
	echo 'Foo bar!';
};

Foo::$bar();

// Work around:

/*
$f = Foo::$bar;
$f();
*/

// Test Case 2:

class Foo
{
	public static $bar = array();
}

Foo::$bar['bar'] = function() {
	echo 'Foo bar!';
};

Foo::$bar['bar']();

Expected result:
----------------
Foo bar!

Actual result:
--------------
Notice: Undefined variable: bar
Fatal error: Function name must be a string
