I am currently actually implementing the most restricted proposal: all differences in the property definition will lead to a fatal error. The reasoning behind this is, that the semantics of state is not predictable and all changes in the class/traits hierarchies which are incompatible should give the developer an immediate feedback, i.e., make potentially incompatible code break. That is not the most 'dynamic' of all possible solutions but seems to fit with the rest of PHP. What I have in mind is also not how the methods integrate into the inheritance chain, thus, a property in the body of the class does not override all property definitions in traits (this is the case for methods). I think that will be useful for the very same reason. And well, I hope an educative error message will steer the crowed in the right direction to use accessors.
