I skimmed over the proposal and it is extremely well thought out, and almost everything that was causing a -1 on the previous RFC is gone: kudos! The last bit that is missing is the `__get` kink, mostly because `__get()` is "squishy by design". Still, the fact that references are properly typed mitigates the issue for my shady use-cases (I've got a reputation there), so I'm quite happy with an implicit magic type check. One thing I couldn't find is whether this magic check is also enforced when calling `__get()` explicitly, and not via the guards in the engine. Is the current development branch usable for testing something locally? I can't see any obvious mistakes here, but I just wanted to try this out with some of the more obscure libraries that touch property state at the level that is covered by this RFC. >
