Supplemental types.

Cell0
class

object

A Sequence implementation always containing a single element.

CellEngineering

The purpose of this type is to provide a means to allow receivers of a sequence to know that the sequence produced in a particular case will never contain more than one element without having to explicitly communicate such a fact with another value sent alongside the sequence.

While an explicit plural field is clear and desirable, it also carries the burden of having to be propagated with the sequence. Having the sequence type designate the constraint allows the information to be propagated without concern by the nodes along the call graph.
