Yes this is what I understood, so changing this would require hacking
around the serialization package.

Thanks for all your suggestions.  I finally worked around this by
transforming the objects referred to to forms that look like (list
'find-object-by-id id) where id is the integer id of the idea.  When I
need the information I then just call funcall and everything works :).
 It also somehow feels faster (I didn't benchmark), since
cl-prevalence doesn't have to recurse into the objects anymore and the
transaction logs are shorter.
