struct arrays and cs-lists

[Jordi Gutiérrez Hermoso]

I don't really understand why if s is a struct array with field foo,
then "s.foo" is a cs-list. What's the purpose of this? How can you get
something like a cell array instead without something as roundabout as
resize(size(s), {s.foo})? Does it have to be this way, is there
something else we can do instead?
