Actually expected result is:

Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
    [6] => G
    [7] => H
    [8] => I
    [9] => J
    [5] => X
)

And that you get when you fix your script like this:

function myForeach( &$f_source, $f_handler ) {

ie. Pass the array by reference. Otherwise you're modifying a copy.

Description:
------------
PHP version 5.3.0-a3.
I think $f_source in the anonymous function passed to myForeach isn't
passed by reference, even though the syntax is correct.
The problem appears when an anonymous function is passed to a global
function in a method of a class. Within that anonymous (nameless)
function the source of the myForeach can't be retrieved (only local and
global can be retrieved), so I pass $list to the anonymous function as
well. When I change a key or unset the member, it's not recorded back to
the original $list.
Which makes me conclude $f_source is NOT passed by reference.

Reproduce code:
---------------
function myForeach( $f_source, $f_handler ) {
        foreach ( $f_source AS $k => $v ) {
                $f_handler($v, $k, $f_source);
        }
}

class SecondClass {
        public function __construct() {
                $list = range('A', 'J');
                myForeach($list, function($v, $k, &$f_source) {
                        if ( 'F' == $v ) {
                                $f_source[$k] = 'X';
                                unset($f_source[$k]);
                                $f_source[$k] = 'X';
                        }
                });
                print_r($list);
        }
}

new SecondClass;

Expected result:
----------------
Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
    [6] => G
    [7] => H
    [8] => I
    [9] => J
)
Notice the [5] => F missing.
-OR-
Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
    [5] => X
    [6] => G
    [7] => H
    [8] => I
    [9] => J
)

Actual result:
--------------
Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
    [5] => F
    [6] => G
    [7] => H
    [8] => I
    [9] => J
)
