  5. def contains_(v: A)(implicit ev: Eq[A], F: Foldable[F]): Boolean

    test if F[A] contains an A, named contains_ to avoid conflict with existing contains which uses universal equality

    test if F[A] contains an A, named contains_ to avoid conflict with existing contains which uses universal equality

    Example:

    scala> import cats.implicits._

scala> val l: List[Int] = List(1, 2, 3, 4)
scala> l.contains_(1)
res0: Boolean = true
scala> l.contains_(5)
res1: Boolean = false
  6. val fa: F[A]
  7. def foldSmash(prefix: A, delim: A, suffix: A)(implicit A: Monoid[A], F: Foldable[F]): A

    Intercalate with a prefix and a suffix

    Example:

    scala> import cats.implicits._

scala> val l: List[String] = List("1", "2", "3")
scala> l.foldSmash("List(", ",", ")")
res0: String = List(1,2,3)
