[Validator] [Validation] Check validation errors by using the OOP way

Hello,

I personally use the Countable "count" method of the ConstraintViolationListInterface

Thanks :)

Thanks Florian. I don't have a strong opinion about this, so let's wait for other opinions.

Classes implementing Countable can be used with the count() function.

https://www.php.net/manual/en/class.countable.php

If, in fact, to implements the Countable interface you do have to declare a count() method, it is an implementation thing, as the primary goal of Countable is to call count($object) ... allowing to count different types of data.

So as early developers see count() more often... i'd say it's better to stay at a higher level.

And they will not hesitate between count() and ->count when they do not know if the "thing" passed is an array or an object :)

Example:

// $foo can be an array or an object

if (is_countable($foo)) {
    return count($foo);
}

Thanks for your time and your explanation @smnandre it is clear enough to close this PR ;)
