Tupled2

case class Tupled2[A, B, Ref[_]]() extends Rel3[Ref[A], Ref[B], Ref[(A, B)]]

Product of two cells.

The flow is unidirectional, from factors to the product, but not the other way around.

Queries have to specify a superset of either both factors, or the result. A query that specifies just one factor doesn't uniquely determine the types of the other columns, and therefore is not considered type-safe.
