Is it possible to use a constant to initialize a case? If it happens, is_int() will fail. Can't we access the type at this moment?

It's possible, and it fails. But not here.

Built-in constants work.
User-defined constants don't: https://3v4l.org/nhGRA#v8.1rc3
Class constants work if the class is defined before the enum: https://3v4l.org/bcYPN#v8.1rc3.
Class constants from autoloaded classes do not work: https://3v4l.org/AjOCi#v8.1rc3
3v4l doesn't have proper 8.1 yet, so it's based on RC3. Some of the above could have been fixed before final release.

I've just built 8.1 branch, and there are no changes for those cases.
