Hi internals, A few months back I sent <https://github.com/php/php-src/pull/15956> for improving the output of `ReflectionClass::__toString()` when used for enums (and `ReflectionEnum::__toString()`, which just inherits that method). Since this is technically a breaking change if anyone is relying on the output of the string representations, it was suggested that I bring this up on the mailing list. Any objections?
