Given that I don't mind mixing in Persistent, what I think would be even 
better would be a way to either:

1. "replace" an existing object (i.e. proxify even existing references to 
it), OR

2. "observe" built-in mutable types such as lists and dictionaries.

Note that #1 means we could do #2, by "replacing" the objects.  Either one 
would permit truly transparent persistence.
