22--EXPECTF--
23Inherited static properties refer to the same value across classes:
24%unicode|string%(8) "original"
25%unicode|string%(8) "original"
26%unicode|string%(8) "original"
27
28Changing one changes all the others:
29%unicode|string%(11) "changed.all"
30%unicode|string%(11) "changed.all"
31%unicode|string%(11) "changed.all"
32
33But because this is implemented using PHP references, the reference set can easily be split:
34%unicode|string%(11) "changed.all"
35%unicode|string%(11) "changed.one"
36%unicode|string%(11) "changed.all"
