scala> import org.http4s.dsl.&
scala> object Even { def unapply(i: Int) = (i % 2) == 0 }
scala> object Positive { def unapply(i: Int) = i > 0 }
scala> def describe(i: Int) = i match {
     |   case Even() & Positive() => "even and positive"
     |   case Even() => "even but not positive"
     |   case Positive() => "positive but not even"
     |   case _ => "neither even nor positive"
     | }
scala> describe(-1)
res0: String = neither even nor positive
scala> describe(0)
res1: String = even but not positive
scala> describe(1)
res2: String = positive but not even
scala> describe(2)
res3: String = even and positive
