Here's a simple test case.

$numeric = 123;
$bool = true;
$foo = array(&$numeric, &$bool);
str_replace("abc", "def", $foo);
array(2) {
array(2) {

While the actual output is

array(2) {
array(2) {
  &string(3) "123"
  &string(1) "1"

IMO this is not the intended behaviour, but also looks like a WFX issue. Note that the same applies to preg_replace() / ereg_replace().
