As long as we don't change this all is fine (because of BC).

The only think i am unsure is the first reult. But it makes
pretty much sense the way it is now. It should compare all
member variables and return equality if they are all equal.
AFAIK it does so. The only difference to 4.3 then is the 5th
result:

class Foo {
  var $v = 1;
}
$a = new Foo;
$b = new Foo;

echo $a === $b ? "same," : "not same,";

In this example $a will be Object Id #1 and $b will become
Object Id #2. Now tell me how those two could be identical?
Every other resut than 'different' is simply bullshit.

This should be the same as with 4.3. Since it obviously
is not it must be fixed or the compatibility mode only
provides weak compatibility and this will become a known
issue.
