Really?  Their absence drove us nuts, because whenever someone mutated
a list directly, it led to confusion and time lost to tracking it
down, so we wrote PersistentList and now use it all over the place.
Perhaps it's because we have lists of things all over the place --
steps, parameters -- while there seems less use for them in Zope,
where things are usually accessed by name.
