A couple more thoughts:

There's a difference between nested data structures and recursion. Use
of one doesn't necessarily imply the other.

Also, whether a given data structure is "nested" or not can depend on
your point of view. Most people wouldn't consider a linked list to be
nested -- it may be "wide", but it's not usually thought of as
"deep". I don't think it's unreasonable to ask for a pickle that
doesn't use up a recursion level for each unit of width in such a
