-It was suggested that instead of restricting ''->'' to be used on all non-enums to restrict access to just non-''readonly'' properties. Unfortunately, this doesn't solve the caching problem described above as ''readonly'' properties can be initialized after object construction and thus becomes non-pure.+It was suggested that instead of restricting ''->'' to be used on all non-enums to restrict access to just non-''readonly'' properties.
