b) A function which returned a variable by reference couldn't be returned by reference. I think this one is probably OK to code. Do you mean a referenced variable returned by a function couldn't be returned as a reference by its caller? That is to say, function &foo() {
        return $a;
} function &bar() {
        return foo();
} $a = &bar();

Yeah there was a bug with this. It should work now. Andi
