In PHP 8, but not in PHP 7.4, every class with a __toString() function implicitly implements the Stringable interface. Therefore, the behavior of checks like "instanceof Stringable" differs between these PHP versions when such classes are involved. Make every such class implement the interface so that the behavior will be consistent. The PHP 7.4 fallback for the Stringable interface is provided by symfony/polyfill-php80.
