Hi Nikita/Bob, I’m *really* happy to see someone taking another stab at this. My only ‘input’ as such, is around the decision to omit `callable`. Given that we *have* Closures (thus allowing a developer to explicitly state that they want something they can invoke regardless of context, if they so wish), I think `callable` should be a valid type for properties too. The language doesn’t prevent floating point math because you might not get the result you expect - it simply documents and warns people that they need to be aware of some inherent attributes of the feature. Whether that particular aspect of the RFC changes or not, again, thank you both for working on this!
