Hi Máté, I think you didn’t understand me, so I’ll restate:
> To be exact, defining class constants with the class itself as value is > already impossible: https://3v4l.org/J7C30 No, for some specific sort of class, namely for enum, it is absolutely possible to define a constant with an effective type of `self`: https://3v4l.org/r8Jo3 ```php enum A { case foo; const bar = self::foo; } var_dump(A::bar instanceof A); // true ``` —Claude
