The RFC and its rationale are presented here as required: https://wiki.php.net/rfc/stringable The patch is found on GitHub, where some discussions happened already, you might be interested in having a look: https://github.com/php/php-src/pull/5083 TL;DR, I think we need an interface to allow passing objects with a __toString() method in a type-safe way, using the string|Stringable type. Here is the stub of the proposal: interface Stringable { public function __toString(): string; } I invite everyone to review the RFC before commenting here as I tried to sum up considerations that some already had before and that you might have too. Cheers, Nicolas --0000000000001d923c059cbc6f83--
