class foo {
        function bar() {
            print 'bar() called<br>';
    $foo = new foo();
    $bar =& $foo;
    $method = 'bar';
    $foo->$method;                   // does not work
    $bar->$method;                   // does not work
    call_user_method($method, $foo); // works
    call_user_method($method, $bar); // works

  I think this is a bug, and all four ways to invoke the method must
have worked at some time in the past (I tested with latest 4.0.7-dev
CVS on Win32), since PEAR uses the first/second method to invoke its
'emulated destructors'.
