So by using PersistentList it just means that you can use:
self.alist.append(1)
in your code. The attribute, self.alist, is still saved even without
PersistentList but it just means you have to be careful when writing
to it.
PersistentX classes also usually subclass Pers
nds like too much work, and would be problem prone even so. After

AA! This is so wrong! It merges two incompatible APIs: collections and
mappings. The non-persistent equivalent to this is:
