[RFC] Property Hook improvements

Hi folks. As Ilija's been polishing off hooks to get the PR merged, we've run into two small revisions that should make life better for all involved. One is a performance improvement that requires a very slight error handling behavior change, and the other is enabling readonly in selected (but probably all of the relevant) circumstances. I'd say we expect these to be uncontroversial, but this is PHP. :-) So I will instead just note that it's a short RFC and open the discussion accordingly. https://wiki.php.net/rfc/hook_improvements -- Larry Garfield larry@garfieldtech.com
