This appears to be the crucial thing: if you declare the test() method 
as static in both classes, it returns false in all versions: 
https://3v4l.org/hJoor

It's almost like A::test() is now interpreted as a static call, rather 
than a "scope resolution" of the instance method, but $this is still 
available, so it's not quite as simple as that: https://3v4l.org/qbT3j
