final case class WitnessAs[A, B](fst: A, snd: B) extends Product with Serializable

WitnessAs[A, B] provides the singleton value of type A in fst and fst converted to type B in snd.

The purpose of this type class is to allow literals of other types than the base type to be used as arguments in numeric predicates.

Example: 

scala> import eu.timepit.refined.{refineV, W}
     | import eu.timepit.refined.api.Refined
     | import eu.timepit.refined.numeric.{Greater, Less}

scala> refineV[Greater[W.`2.718`.T]](BigDecimal(3.141))
res0: Either[String, BigDecimal Refined Greater[W.`2.718`.T]] = Right(3.141)

scala> refineV[Less[W.`1`.T]](0.618)
res1: Either[String, Double Refined Less[W.`1`.T]] = Right(0.618)
