Laravel 8 makes it possible to create custom Validation rules: https://laravel.com/docs/8.x/validation#custom-validation-rules
php artisan make:rule Euro
But then you have to pass the rule as a object (instead of a string):
new Euro
instead of the regular string notation
'required|euro'
Is there anyway to "register" the new Rule classes to a string identifier and use them like you can you the pre-existing rules?
