  5. def count(p: (A) ⇒ Boolean)(implicit F: UnorderedFoldable[F]): Long

    Count the number of elements in the structure that satisfy the given predicate.

    Count the number of elements in the structure that satisfy the given predicate.

    For example:

    scala> import cats.implicits._
    scala> val map1 = Map[Int, String]()
    scala> val p1: String => Boolean = _.length > 0
    scala> map1.count(p1)
    res0: Long = 0
    
    scala> val map2 = Map(1 -> "hello", 2 -> "world", 3 -> "!")
    scala> val p2: String => Boolean = _.length > 1
    scala> map2.count(p2)
    res1: Long = 2
