Any persistent instance can store a list (and it becomes
persistent). You must be careful however, when you change the list
to tell the object that it changed.

Alternatively, you can use a "ZODB.PersistentList.PersistentList".
In this case, the list itself is persistent and modifications to
it are automatically written to the storage.

Modifications to sublists are not automatically recognized, though.
