--TEST--
Inherited static properties cannot be separated from their reference set.

class C { public static $p = 'original'; }
class D extends C {	}
class E extends D {	}

echo "\nInherited static properties refer to the same value across classes:\n";

--EXPECT--
Inherited static properties refer to the same value across classes:
string(8) "original"
string(8) "original"
string(8) "original"

Changing one changes all the others:
string(11) "changed.all"
string(11) "changed.all"
string(11) "changed.all"

References cannot be used to split the properties:
string(11) "changed.one"
string(11) "changed.one"
string(11) "changed.one"
