object Tuple2
Stage projections for Scala's standard scala.Tuple2 type.
Each projection extracts one element of a pair (A, B) and always yields h8io.stages.Yield.Some with
h8io.stages.Status.Success, because a tuple always has both elements.
Example:
val fstStage = Tuple2.Left[String] // Stage[(String, ?), String, Nothing] val sndStage = Tuple2.Right[Int] // Stage[(?, Int), Int, Nothing]
