Hi Levi.

I have plans to bring an `array_find_first` and `array_find_last` to the
next PHP 7.x. It will basically work:

    $firstUserWithUsername = array_find_first(function (User $user): bool {
        return $user->username !== null;
    }, $users);

Just wanted to point that to alert that someone is working on that :)
