All checks have passed 🎉 @TomasVotruba I think it is ready.

I think this is rather specific fix that will fail for slightly different code syntax. There should be check for first type of $code or if the value type changed.

How would this behave with negated value?

$ok = ! \is_string($code) && self::isCodeOk($code);

[samsonasik]

negation check is invalid and will cause fatal error on the first place, since it typed param string on caller, see:
