  6. def combine(lx: Eval[A], ly: Eval[A]): Eval[A]

    Associative operation which combines two values.

    Associative operation which combines two values.

    Example:

    scala> import cats.kernel.instances.string._
    scala> import cats.kernel.instances.int._
    scala> import cats.kernel.instances.option._
    
    scala> Semigroup[String].combine("Hello ", "World!")
    res0: String = Hello World!
    
    scala> Semigroup[Option[Int]].combine(None, Some(1))

  7. def combineAllOption(as: IterableOnce[Eval[A]]): Option[Eval[A]]

    Given a sequence of as, combine them and return the total.

    Given a sequence of as, combine them and return the total.

    If the sequence is empty, returns None. Otherwise, returns Some(total).

    Example:

    scala> import cats.kernel.instances.string._
    
    scala> Semigroup[String].combineAllOption(List("One ", "Two ", "Three"))
    res0: Option[String] = Some(One Two Three)
    
    scala> Semigroup[String].combineAllOption(List.empty)
    res1: Option[String] = None

  8. def combineN(a: Eval[A], n: Int): Eval[A]

    Return a combined with itself n times.

    Return a combined with itself n times.

    Example:

    scala> import cats.kernel.instances.int._
    scala> import cats.kernel.instances.string._
    
    scala> Semigroup[Int].combineN(1, 10)
    res0: Int = 10
    
    scala> Semigroup[String].combineN("ha", 3)
    res1: String = hahaha
