Given that:
class foo {
function bar() {
$this->a = 1;
$ref = &$this;
$ref->b = 2;
$ref = null;
}
}
$x = new foo;
$x->bar();
echo $x->a, $x->b;
Outputs 12 and doesn't appear to cause any major badness internally, I
don't really see any reason to disallow it. If an E_STRICT could be
raised without affecting performance too much that would be good since
it is a useless assignment. Given the lack of badness on the php5 side
and the high level of goodness for php4 portability, I say leave it as
it is now.
