New RFC just dropped: https://wiki.php.net/rfc/default_expression. I think some of you might enjoy this one. Hit me with any feedback.


Now the dust has settled, I've updated the RFC to version 1.1. The premise of the RFC is unchanged, but the proposal has been expanded and a discussion section added to summarise the ~100 message thread to capture the major concerns raised in a condensed format. I hope I've done a good job of fairly and accurately representing your concerns, but if not please correct me.



As promised, I have written up a full explanation of the type safety issues here: https://wiki.php.net/rfc/default_expression/type_safety

I have tried to write this as a neutral description of the problem and the possible approaches we could take, to be inserted directly into the current RFC, rather than as a counter-opinion or a narrative of who said what.

I have included the 4 options which I believe are the only ones we have; it is then a matter of opinion which we think is best. For the record, my opinion remains that option 3 (limit to conditional expressions) is preferable, but I have assumed the RFC will continue to advocate for option 1 (allow any expression and assume problems will be rare).

I hope I have explained it clearly enough this time to overcome the previous misunderstandings of where the issue lies.

Regards,
