CI4 = end of fatal errors

I just want to point one important thing in PHP 7 - http://php.net/manual/en/language.errors.php7.php

Most of our loved PHP errors will be Throwable inside the new PHP version.
I hope that CI 4 will use this error improvement of PHP and at future we won't have any more PHP errors but instead they will be fully controlled by the framework.

Of course while PHP don't have 100% throwable errors there will be always cases which can't be covered.
