        return new Some($thing);
    } else {
        return new None;
    }
}

function findSomethingElse(): Result {
    // ...
    if ($foundSomething) {
        return new Some($thing);
    } else {
        return new None;
    }
}

// Fallback to value
$value = findSomething()->unwrapOr(null);
