I just before pushed a third implementation idea which addresses this. It also no longer requires a separate cache. It uses the store itself.

I also don’t see how this would solve the get hook issue? As a user I want to be able to have a get hook in readonly classes. For instance, for formatting. In my last answer to Tim I showed an example of what I would expect from readonly properties. Cheers, Nick
