It seems like $ranges->expand() targeting UCD\Unicode\Codepoint\Range\Collection::expand() can also be of type array<integer,object<UCD\Unicode\Codepoint>>; however, UCD\Database::getByCodepoints() does only seem to accept object<UCD\Unicode\Codepoint\Collection>, maybe add an additional type check?
