[Discussion] Make objects unpackable by default

Hello, Internals! As you know if you try to unpack a regular object (...$object) you will get an error: Only arrays and Traversables can be unpacked. I don't really see a reason for this restriction, because foreach on objects works perfectly fine, so I made a feature request on GitHub to change this behavior (https://github.com/php/php-src/issues/16038) and was advised to see opinions on this here. So, what do you think? And does this change require RFC? Best regards, Ilya
