What does the reduce metaoperator do with an empty list?
Interesting. Mathematically an empty sum is zero and an empty product is one. Maybe each operator {c,s}hould have an associated method returning its neutral element for [] to use it on empty lists, so that it would probably return undef on empty lists.
