Hi internals,
I have closed the voting. With 38 in favor and 28 against the RFC is DECLINED
(didn’t reach the needed 2/3 majority for a new feature).
Thanks to everyone who has participated.

I consider operator overlaoding in general a good feature (whil
I accept that it adds an extra level of understanding to the language – if
you see

you no longer definitely know the answer will be numeric.

Hi, internals!
I want to mention, that all existing internal API of Zend could be
accessible via FFI as of PHP7.4. This gives opportunity to implement
userspace operator overloading as a simple PHP package.
I know, that FFI requires some polishing, but it could become a tool to

Hey Jan,
Just posting here why I voted "no": it is not your implementation proposal,
but rather the concept per-se that IMO shouldn't land in the language.
Operator overloading makes call-site code reading extremely hard, and it
makes the language much more complex for very little benefit.
