This should work.

I found these snippets:

https://psalm.dev/r/e9cc52c5ef

<?php
namespace A\B {
    class Foo {
        /** @psalm-internal A\B */
        public static function barBar(): void {
            self::barBar();
        }
    }
}

Psalm output (using commit da802a5):

ERROR: InternalMethod - 6:13 - The method A\B\Foo::barBar is internal to A\B  but called from A\B\Foo
