I agree with Jonathan.

Please do not make them a subset.  Make them as identical as possible. 
The subset thing makes them no longer "swappable".  Allow variables to 
be marked with @property to limit them to operations that @property 
functions can do, and make sure @property functions are limited to what 
@property variables can do (ex: no address-of!).  With that in hand, 
they'll be very swappable.
