2017-03-10 Paul Boddie Prevent __data__ accesses via anonymous accessors from trying to find the attribute on classes since __data__ is always provided by the immediate object and because the check_and_load_via_any operation uses a null value internally to detect failure that can be confused with a genuine __data__ attribute with a zero value (such as the integer zero).
