I while back I made a suggestion for cloning which seemed to resolve the cloning issue in a way that no other proposals do. However, no one acknowledged it, so maybe few if any people saw it? https://externals.io/message/114729#114747 <https://externals.io/message/114729#114747> Anyway TL;DR, the approach is to allow specifying a closure on clone, binding $this to it, and then allow modifications to readonly properties while in that context and anything that it calls: $clone_obj = clone $obj fn() => { $this->foo = 'new value'; } Would this not be a viable solution for cloning, for this RFC, or the only you work on if this one fails to pass? -Mike
