There are some notes on PHP RFCs, why some were declined, and what others might need for them to be implemented.

The purpose of these documents is to avoid information from being lost and to try to avoid conversations needing to be repeated multiple times on PHP internals.

Class scoping improvements

Consistent callables

Enums

Explicit defaults

Generics

Method overloading

Named params

Strings/encoding is terrible

Disclaimer

I reserve the right to be as opinionated as I feel like when commenting on RFCs; I'm not going to attempt to stay 100% neutral when talking about RFCs that I consider to be either dumb or bad for PHP.
