Hi internals,

I'd like to present an RFC for property accessors:
https://wiki.php.net/rfc/property_accessors

Property accessors are like __get() and __set(), but for a single property.
They also support read-only properties and properties with asymmetric
visibility (public read, private write) as a side-effect.

The proposal is modeled after C#-style accessors (also used by Swift), and
syntactically similar to the previous
https://wiki.php.net/rfc/propertygetsetsyntax-v1.2 proposal.

While I put a lot of effort into both the proposal and the implementation,
I've grown increasingly uncertain that this is the right direction for us
to take. The proposal turned out to be significantly more complex than I
originally anticipated (despite reducing the scope to only "get" and "set"
accessors), and I'm sure there are some interactions I still haven't
accounted for. I'm not convinced the value justifies the complexity.

So, while I'm putting this up for discussion, it may be that I will not
pursue landing it. I think a lot of the practical value of this accessors
proposal would be captured by support for read-only (and/or private-write)
properties. This has been discussed (and declined) in the past, but
probably should be revisited.

Regards,
Nikita
