        foreach ($this->visitors as $v) {
            $v->init($collection, $file);

The method init does only exist in Translation\Extractor\Visitor\Visitor, but not in PhpParser\NodeVisitor.

            $traverser->addVisitor($v);

It seems like $v defined by $v on line 37 can also be of type object<Translation\Extractor\Visitor\Visitor>; however, PhpParser\NodeTraverser::addVisitor() does only seem to accept object<PhpParser\NodeVisitor>, maybe add an additional type check?
