[elephant-devel] Mutating slots persistently?

Hi,

How do people deal with the following problem... suppose I have a
persistent object with a slot that holds a list. And I mutate the list
with RPLACA. (Perhaps an innocent-looking SETF which expands into
RPLACA.) Well, this won't be stored persistently.

How do people deal with this situation? Basically just always use
methods which set the entire slot? Are there any tricks to keep from
having to do this?

Thanks,
Tayssir
