Re: [RFC Proposal] Add #[NoSerialize] attribute for excluding properties from serialization

Hi Dmytro Thanks for your proposal. This seems like a reasonable use of attributes.

A few things: * How does this interact with inheritance, i.e. is this flag inherited to overridden child properties? I would assume no, as with other attributes. But it would be good to spell it out. * There are other forms of serialization, most notably JSON and var_export(). Are these affected in any way? Does it make sense to have a universal solution? * There may also be a benefit to marking classes as entirely not serializable, which would throw when encountering the class during [un]serialization. We have some of those internally. [^1] Ilija [^1]: https://github.com/search?q=repo%3Aphp%2Fphp-src%20%40not-serializable&type=code
