Prior to 4.0.6 it worked fine, however, now when I try:

$result = call_user_func("foo", &$bar);

function foo( &$bar ) {
   $bar .= 'foobar';
   return 1;

I get this:

Warning: Call-time pass-by-reference has been deprecated - argument passed
by value; If you would like to pass it by reference, modify the declaration
of call_user_func(). If you would like to enable call-time
pass-by-reference, you can set allow_call_time_pass_reference to true in
your INI file. However, future versions may not support this any longer.

Does that mean I can't pass by reference anymore? I kinda need to (the two
functions above are not my actual functions btw)....
