I think for this question, the one-and-for-all solution is. to have a fully
incremental persistent object store, i.e. all mutation are stored
incrementally without ever needing to print out the “fully value”
of a Lisp value. What do you think?

resist!.el in its current form basically implemented a special case
of the above, where only mutation to the top level hash table 
is persisted incrementally.

I can’t see a way to implement persistent object store without
some non-trivial memory overhead, though (because each
object has to get an unique id). The best thing I can come up
with has to have a hash table that maps every object in the
store to a numeric ID. Is that too much?
