[cl-store-devel] serialized class instance as document format

[Sven Emtell]

Hi all
I am planning to use cl-store to save and load documents in an  
application that I am developing.
What I want to save is a serialized class instance using cl- 
store:store and then later be able to load it using cl-store:restore.  
What troubles me is that in future versions of my application, there  
may be new slots in the class. My tests reveal that such new slots end  
up being unbound when loading an old class instance (without the  
slot). Instead I would like it to have the new slot set to  
it's :initform value.
Is this possible?
Any thoughts on using a serialized class instance as document format?
Thanks!
Sven
