It seems like $address defined by parameter $address on line 79 can also be of type object<Recca0120\Twzipcode\Address>; however, Recca0120\Lodash\JString::__construct() does only seem to accept string, maybe add an additional type check?

The expression $matches of type null|array<integer,array<integer,string>> is not guaranteed to be traversable. How about adding an additional type check?
