I think the issue is that you're missing a namespace

Interesting. I isolated it from code which had namespace...

So in this issue let's focus if the class is the same, with self:: it always is. Root namespace should be computed from the full class name.

Not sure to understand. You should give a real example with namespaces then.

In simple words, https://phpstan.org/r/6e30fb04-d096-42d1-a0b5-7d0672c9c684 (repro from description) should not report any error. The class is not namespaced, but the access is withing the same class, thus internal access is fine.

I mean the NS for computing "root NS" should be computed from the NS incl. class name, ie. "root NS" for the declaration and the access would be "HelloWorld". This only an idea for possible implementation.

Then does phpstan/phpstan-src#3998 solve your issue ?

That is exactly perfect, thank you! ❤
