First, look att this piece of pure PHP code:
$s1 = new S();
$s1->a = 42;
$s2 = new S();
$s2->a = 4711;
$s2->x = $s1;
$s3 = $s2->x;
All three of the "echo" lines above will output the value 42.
Now consider the same code, but S is class in a PHP extension that has
implemented the handle_property_get function to retrieve properties.
This time, the last echo line will get the value of $s1->a and not $s2->a.
handle_property_get is only called on the $s1 instance and not on the $s2
instance of the object.
I will write a PHP extension that just shows this "feature".
